Added to OP.

And Vita for the most part.

Not unless it's...

1) Cancelled (Sony won't let this go!)

2) Delayed to 2013

3) Developed by another dev

4) Another game besides Black Ops 2

Overall, no CoD for 3DS is bad, but nothing that would severly damage it. Terrible for Vita if it's 1 or 2. 

Looking at this companies output it's probably a good thing for the Vita version that they're not the ones working on it.

Yeah, I don't think it would've been as high-quality as the console versions if they made it. The DS games were nothing at all.

No MH and now no COD for Vita? What's next, no err... well, nothing huge left.

Lol, of course not, it'll come, both of them. If not by this developer, by some other, this fall.
