well since there is no Shitlistic anymore, MW4 Vita might be done by poor Raven or any of Acti devs,so it (well if acti announce it for Vita) might be decent and full port,they got a good track record with the Wii.
Even if the vita version of COD was by far the best version of COD ever released I wouldn't get it. I tried COD 4 and MW3 and couldn't stand either of them. Dreadfully boring games for me. I would much rather have something like timesplitters lol.
Even if I did like the series though I wouldn't get it on the vita. I don't go out to often, and when i do I tend to bring stuff like my psp or ds instead of my vita or 3ds as if my psp or ds break it's not that expensive to replace them (or if someone stole them) thus portability for a game like COD isn't a big deal for me, I would rather just play it on a console on a bigger screen if I was going to play it.
As for disney... well if I played it it would be co op with my wife... co op on a single vita system doesn't work so well

sign up to pick up a physical copy of class of heroes 2.. only a few more days until the chance is gone and if the goal isn't met no one will get them. While it is a psp game and the vita doesn't support umds it's an odd choice, but given it will come with a digital code, and vic has said that vita compatibility is a must for him even if you pick up a physical copy you will be able to play it on your vita. Plus given the low print run of they physical copy, it will likely hold it's value well and be cheaper to buy a physical copy for $35 and sell it after you take the code then buy the digital copy for $25
