Well Red Alert 3 has a PS3 version ^^
So ye, they try to make good games only for xbox so they could sell xbox in the first place, since they are losing battle on other market fields. No one buys theyr hardware since there are beater from other companies (not to mention Max), theyr operative system is going down, cuz vista sucked, and Linux is taking over, or people are at least staying at xp, so Microsoft still doesn't get to sell anything...
