Dont bet on it.

Using similar codenames for "unrelated" products within a company is not unheard of you know... Im guessing its Diablo 3.

Of course it's Diablo III. We all know Blizzard has been looking for people to work with the team that created Diablo.

Hydra = 3 heads. Diablo III.

A Diablo MMO perhaps? Either way I believe it's Diablo related.

Guessing, It's probably Diablo 3... Blizzard doesn't like diverting from it's trinity of franchises

Diablo 3, I'll bet money on it.

wow hopefully its diablo 3, i have been waiting for a third diablo. diablo 2 was so fun

maybe its the codename for a secret cow level???

The team that created Diablo left Blizzard almost 3 years ago. That whole group (i.e. Blizzard North) including Blizzard co-founder Bill Roper defected and formed their own game development company called Flagship Studios. The "true" spiritual successor to Diablo 2 is the upcoming Hellgate: London. Who knows if Diablo 3 will ever see the light as we once knew it, unless they are perhaps looking into developing another MMO based around the Diablo mythos. Frankly, for the sake of variety, I would harbor a guess that they are instead working on a more futuristic MMO based on the Starcraft universe. Why create another fantasy based "Sword & Sorcery" MMO when WoW is still running so strong?

well u make a good point but im saying they could finish it to add to the story, maybe do a diablo 2 type game wit better graphics lol who knows.

Blizzard could very well be hiring people with MMO experience for work on Diablo 3. Considering the huge appeal of that franchise and how much people played that game on Battlenet, using some sort of MMO structure (say Guild Wars, i think) is probably very much something Blizzard could do.

I'm not convinced the the codenmae Hydra has anything to do with the Starcraft franchise. Medusa has links to both the Diablo and Starcraft franchise and these linsk were analysed during the lead up to the announcement of Starcraft II so it is safe to say that we can't speculate about Blizzards names. Hydra could also have links with the Warcraft and Diablo franchise if you look closely enough so to say, "Hydra = Starcraft," is a little premature.

It is true however, that releasing a Science Fiction MMO based on the Starcraft franchise would be a logical step for Blizzard. At the moment, they are dominating the fantasy genre but with Star Trek Online, Stargate Worlds and rumours of a new Star Wars MMO springing up all over the net, Blizzard might be planning to try and take the market from these three major titles. On the other hand, Star Trek, Star Wars and Stargate are far bigger franchises than StarCraft simply due to the Pop Culture status of each entity so it is a risky move if it is what Blizzard is doing.

And if you look at the below posts, the speculation has already been destroyed by even more speculation. My advise would be to place no expectations on Blizzard.

Also, if the codename is out now, I expect an announcement of the game after WotLK/Starcraft 2 are released but we also have to remember that Blizzard have said Warcraft 4 could be a possibility after StarCraft 2 ships.

World of Starcraft :P Naah too obvious...

They will not launch World of Starcraft as a Wow-style MMO. Not a chance. Nor will they launch it as a Diablo style "MMO". They might however launch a game much like Planetside with some glances at Battlefield and Quake Wars. Why? Because a WoW style Starcraft game would be bad. There is a lot of things lacking for a game like that to succeed (IMO). And/or people would try the game, and lots would quit WoW, especially in their Asian markets. This is not a good thing for Blizzard. I would expect a Starcraft MMO once WoW players start declining worldwide.

maybe its a new Warcraft RTS game? or it could be an entirely new game all together.

I don't agree. You see, the thing you have to take into account is that, as long as you are still playing a Blizzard MMO, they still earn money and whilst their costs would increase, they have 1000+ opeteron servers that are just hanging around somewhere that they aren't using for World of Warcraft at this moment in time so they are obivously preparing for some major MMO. Also, Blizzard have a habit of, "tried and tested," which means they don't like to take a game and make it revolutionary. It makes them more money to elaborate on things that are already tried and tested.

They may face an exodus from one game to another in the event they release another MMO but you seem to miss the key point here. They are going from one MMO made and owned by Blizzard ot another MMO made and owned by Blizzard... NCSoft own multiple MMo titles including City of Heroes and Villains, Tabula Rasa, Guild Wars etc. Where is the problem with having multiple MMO titles?

The thing with NCSoft is that they have several different types of MMOs. They might steal some players from eachother, but at the moment Blizzard has pretty much capped their pure RPG capacity. Putting out one more game would pretty much ONLY steal players from WoW. It will most likely not make any of the people who quit play again, another expansion (WotLK) will do that nicely however, another expansion also allows them to compete with the new fantasy RPGs: AoC, WaR and whatever else is on the horizon. A PvP-FPS MMOG however would tap into that relatively empty market. It would also fit the franchise more imo. 3 factions with only two that actually use melee weapons, extremely varying types of attacks skills/base health, no proper classes for one faction (zerg sort of). It does however lend itself quite nicely to AVP type MMO. All this is obviously theoryBlizzarding, but its also common sense. Where did you hear about the servers btw?

yes its diablo for sure
