With respect to Gears of War 2, I highly suspect m$ didn't have it ported because they'd rather only put it on 360, where they know the gamers are dumb enough to be milked for costly p2p online and DLC packs that PC gamers would never pay for, not to mention there are no licensing fees for PC either that end up in the pocket of m$.
m$ would probably love for PC gaming to die - if everyone were to migrate to 360, they'd make a lot more money that way.
