Is not a rumor... it's confirmed. This are some quotes:
“Man, we can definitely talk about the Wii Version, I mean, where do we start? Well, first and foremost, The Wii version is being developed here at Treyarch. It’s a separate team from the next-gen team but its on-site. If you’re going to compare the next-gen version and the wii version side-by-side then you’re going to find that it’s a much closer comparison than, I think, any other Wii game currently on the market.”
“Yeah, the challenge with this one was ‘how do we make a cutting edge next-gen game work on the wii’?’. The answer is a lot of frickin’ smart engineers who’ve shipped Wii titles in the past. Getting the call of duty 4 engine on Wii was our first challenge - which we’ve managed to do and it looks great - but there are also a content and design challenges to consider.”
“Beyond that, We’re reall accepting the fact that the person buying on the Wii is doing so for a different kind of experience. I mean, we’re going to be supporting the Zapper and, I don’t know how familiar you are with the Zapper personally, but you lose about five or six buttons on that controller, so it’s very challenging to make a call of duty game that functions well. We’ll be doing some unique stuff with co-op gameplay, too, but we’re not ready to talk on that yet. I honestly think you’ll see what we’re taking the Wii very seriously.”
So, Call of Duty 4 engine is running now on the Wii. Nice.
