Itll sell s good as the Wii versions do. Im serious.

As long as 360 and PS3 versions exist, all other versions will flop in sales.

Call of Duty: Roads to Victory - 2.02M

Medal of Honor Heroes - 2.52M

Keep in mind these were slow burners, but I think FPS games are more suited for Vita. 

I guess it all depends on how well they manage the multiplayer component.And the controls.
If they can bring a similar experience to that on the consoles,then it will be a huge success.

COD on the Vita will be terrible. It won't sell at all. No one want's to play COD on a mini screen. What a joke..seriously! I'm the biggest COD fan ever but the thought of playing on anything smaller than 32 inches doesn't make sense.

Since multiplayer is the main reason people buy COD and you can't play multiplayer over 3G i don't think it will do well at all.

If Actvisition finds CoD vita successful we can expect a yearly release with little improvements over the last installation.

i think it would need to release in the summer and have a huge market blitz! it it launches with the home system versions and is the same game it will flop

C'mon people, the Vita is not domeed...
To me, the vita will do great both in the west and in Japan (yes, just wait for it), the 3DS early months were so-so and now look at that monster. It will happen the same to Vita.
CoD Vita could do really great, if the dual analog sticks are appropriate to shooters and Vita is as powerful as PS3 I see selling millions, it won't be a system seller but it will be successful.

As for me, I don't think I will buy a Vita anytime soon, I still want a 3DS and Sony products disappointed me this generation.
