Eh, I think its too early in the cycle to say this year. I don't know personally but I'd say earliest would be next fall.
Its announced but the ball is rolling down the hill, looks like we have the important stuff, story, characters, and such developed, which is wise before announcing a game of this magnitude.
The getting it done, shouldn't take a long time unless something goes wrong. The networking will be the part that needs tweaked up and worked on most, without that its nothing. That shouldn't be real bad with D2 already in experience, but I'd predict that all that would be worked on next summer/fall and released the next year.
So yea... Maybe late next year, but I doubt it unless things go well which they could, but better be safe than sorry.
