In Japan, yeah. But what resources are they really expending there? What's it cost to make Patapon?
Gravity Daze is a SCEJ nope?
I doubt COD will help it at all. People don't want handheld COD, they want console COD.
To name an example, GTA games worked really well when they got a decent portable version in PSP.
Both tech wise and control wise, it's the first time FPS and TPS games can be implemented properly in a portable.
Considering CoD have astonishing sales in home consoles, if the fans see a proper portable CoD would buy it, like they did with GTA, Mario, Mario Kart, GoW, etc. Not at the same scale than the console versions, but would sell several some millions if properly adapted (ex.melee using touchscreen/waggle, short SP levels, on-line multiplayer, etc).
Same goes with IPs like Bioshock, RDR (included in a leaked/fake long game list of Vita games under development), Battlefield etc.
Considering that it's easy to port the engines, Vita can do a great job in US thanks to third party FPS/TPS.
Europe, as always in the PS history, will be Vita's main market even they don't release a shit or even it will be more expensive here, as always.
The problem is Japan. There are a lot of games that would have good sales there like SFxT, MGSHD or FFXHD, etc but they are going to be multiplatform games.
Sony really needs to steal Monster Hunter 4 for Japan.
Regarding Vita HW sales, we also have to consider PSP is still alive there, like happened with PS2 when PS3 was released, unlike 3DS vs DS, Wii vs GC or X360 vs XB. We also have to consider these 9 days numbers are almost 400K, so maybe they just shipped 400K in the launch shipment, and it's being supply constrained. In any case, we have to consider that the launch games didn't included a big seller in JP, even some of them are important in western markets.
