I didn't see it mentioned here yet, but according to IGN and GoNintendo, Mortal Kombat: Armageddon is coming to the Wii in early 2007!
I'm stoked. I love most of the Mortal Kombat games (with some exceptions, mostly with 4 and the crappy spin-offs around that time) and this one supposedly has everybody...like Mortal Kombat Trilogy, but including everyone in the second "trilogy" (well, all previous games, really - that's probably 60 characters or more) and in 3D (Deadly Alliance and Deception proved that Mortal Kombat in 3D is actually pretty good, after the horror that was 4). I like "dream match" games, and thanks to the apparent lack of permanent death in the Mortal Kombat universe (ironic considering the Fatalities), they'll probably have a decent story-based reason why everyone's back (unlike King Of Fighters or Capcom Vs. Everybody).
When I heard that it was coming to the Xbox and PS2 but not GameCube, I was surprised, since Deception had exclusive boss characters. Now that it's coming to the Wii, maybe it'll get a next-gen treatment and it should be able to have online play, I'm guessing.
Though I remember Ed Boon being hesitant about the controller. Maybe it'll use classic controls (like SSBB will supposedly have)?
