Namco vs Capcom rumored to be in the making right now but with a catch in that its really 2 seperate games instead of one. Namco is making Namco vs Capcom with the Tekken style while Capcom is making Capcom vs Namco with the Street Fighter style. If done correctly it would end up how SNK vs Capcom was a 2 game series since each side made its own version.

Rumored Call of Duty Pay to Play idea rejected by both Infinity Ward and Treyarch for at least the upcoming Black Ops game and current Modern Warfare 2.
Sony investing in using 3D glasses as a way for 2 people to play a split-screen game in a way that each person gets to see the whole screen instead of the traditional bar to split the screen in a game. Only catch is 2 sets of 3D glasses with a 3Dtv is needed and doesn't work beyond 2 players.
