the inevitable is that games are becoming more multiplatform. epic can make more money if it is multi than a deal with ms. it is easy to predict a game like gears because it is on such an obvious path. unreal is that path.
and for the bioshock thing:

yes i understand that nothing is confirmed from t2, but come on. multiplatform than dropping a sku? many people predicted a timed exclusive before these came up, but this just nearly confirms it.
and it is different from ff and mgs, because there have been 0 hints that it will be multi, except for one time but that was soooooo long ago and they said it couldnt be done on 360.
