Yes without any optional equipment. All PS3 models play or can play all the games made for the PS3 for the move only games they would need the PS3 updates and Move controller and PS3 eye camera, but neither is required for MW3.
It all depends on how you play and what you like about it.
You can play MW3 on the pc, XBOX 360, PS3, and Wii.
You cannot play infection on mw3 wii version. But people found it by hacking.

No they are no longer working on Black Ops at Treyarch. Map Packs do not get released to compete with the new Products like MW3 in the Call of Duty Series that is marketed by Activision.

No.
no but those are very old games u should get MW3 and enjoy the online play. Add: If your talking mw2 and mw3 then they are almost exactly the same game play. It doesn't matter.
