That rounds it down to, well, just one title. Craig said during his interview:
I did Call of Duty: Modern Warfare as Gaz and then I did Ghost in Modern Warfare 2, which has become one of the most iconic figures in the history of computer games, which is great. And I've just been out in LA doing something that's going to be announced in May...I've just been out there doing some bits and pieces and one of it's to do with...I can't say too much.
You do like five, six, seven sessions and they record it in this great big studio in Los Angeles, which is absolutely mental. It's incredible. This place was like the size of 10 factories, there was all these people working.
This better be an absolutely mind-blowing game for $200 million to make, I'm willing to wager it'll be on the same graphics engine and will simply be another outing in the Modern Warfare universe, sans Infinity Ward duo.
Thanks to Chris for this!
