One last addition also (Again not trying to go after microsoft but just an observation)
When the PS3 launched the PS2 was supported for quite some time after the fact.
When the 360 launched the Xbox was more or less brought out to pasture.
So even once the PS4 launches your likely to get several more great games on PS3 after the fact. One of PS2's best games came after PS3's launch very late into the PS2's cycle (IE Persona 4)
