Next year should be definitely named as the Year of Strategies:
GalCiv II: Dread Lords. ETA: end of the year (Christmas. Damn marketers)

Comm.: direct competitor of SE V as you know. Will be interesting to see this battle for title of the best 4x game. Official site is only availiable to GalCiv purchasers, though. Are there some Subscribers here to share info?
[rant]Why the hell a crappy sketches of GC2 ships are in the TotalVideoGames.com preview, but beautiful SE5 intro screens can only be found in the malfador site? I seriously think that shrapnel should consider changing/improving their marketing strategy. Or should we write a preview ourselves as soon as screenshots will be availiable and then use blackmail and grafts to publish it in the Online gaming magazine?[/rant]
Civ IV. ETA: 2005 (no quarter info, but probably end of the year).
No offsite yet. Info here:

As always Sid promises us a completely new game. Let's wait until demo will come out for a final judgement. I have to notice that it will offer a couple of powerful technologies for modders - Python + XML. Its combined power could make Civ4 the most moddable game ever. But it's not a fact, just probability.
Did I miss some interesting game which will be published next year?
