Call of Duty on the Vita has the potential to be really g ood, or really bad, but it depends on how Sony/Activision handles it.
A COD PS3 port on the Vita sounds like a bad idea, like someone else said, why get it on the Vita when you can get it on the PS3/360. It will also be harder for guys playing on the Vita. Cross game play is nice, but Vita guys will have a major disadvantage.
On the other hand, an exclusive COD on the Vita that uses the Vita's features to its advantage, similar to that COD game on the PSP will do better. All Sony needs are bundles, and proper marketing.
One thing that nobody went into detail about is COD on the 3DS. COD4, and WaW did pretty well to be on the DS, so it wouldn't surprise me if COD was on the 3DS this year.
