Well, i can't see it happening in short term. For whole entertainment industry i could say Spider-Man 4 or something like that could do it, but for gaming industry only, i think just in next-gen or next-next-gen. 

Modern warfare 3...so 2 years

$$$ record sales record 360 or PS3 record what, be more specific.

nothing ...

perhaps during the next generation

Revenue record, for both gaming only and entertainment industry like a whole.

Like I said, for gaming is just don't see it happening til next gen, maybe a Blizzard release like StarCraft 2 could make with luck.

For entertainment I can see Spider-Man 4 movie, Harry Potter 7 movie.

There's going to be a Spiderman 4?

GTA5

obviously.....seriously no-one thought of it yet

Next GTA, Halo 4, Spiderman 4 [if it's actually good...], Transformer 3, IW Call of Duty

It will be one of these.

next GTA maybe? or next COD... if GT was mulitplat then GT5 for sure

Not really. Gran Turismo's tend to sell over time.
