it will do ok in sales, but only if it plays offline and online like its console brothers. i will check it out, but wont buy it unless there is added extra value in content.

A million or so per entry. People will prefer playing on the big screen.

I just don't think fps work well on a tiny screen, despite the psvita having the nessessary controls to make it work. Everything will either be way too smalI or there will be very very little that you will be able to see on the screen. I predict less then 3mil unless people can unlock weapons and rank up their ps3/360 characters with the psvita version. CrossPlay wouldn't work imo because vita players will be at a huge disadvantage with the tiny screen, but ranking up your main character with the vita version could attract some of the more "hardcore" cod players.

Depends on how good it will be... if a bad port from the next CoD: 1m to 2m ww. If a good port from the next CoD: 3.5m to 4.5m, and it its a totally new game but good: 5m+

My thought exactly,fps became suddenly popular on consoles when people change  from SDTV to HDTV.Still,I think it will do around 2-3 millions

I believe it will have a lot of competition with the consoles version (PS3, Xbox360 and WiiU) and at least I am more interested on a console version of this genre of games.

Depending on how they'll market it.

I've always felt if they made a commercial of the game with a bunch of kids playing against each other in class that'll definitely sell. Just my idea lol

Until FFX and CoD are released, I don't expect it to fly off shelves any time soon. MH Tri G could have seen Sony ship 1million units by years end.

I expect it to sell like The Legend of Zelda: Ocarina of Time 3D.

With vita being the only option to play an HD version with dual thumb sticks, it could be suggested that it will sell nearly 20M copies. Possible if it picks up both the X360 crowd and the PS3 crowd of home console MW games.

However, being on a Playstation in current times, and being portable. I will be happy if it sells over 4M lifetime.
