On the subject, Kojima is out of his goddamn mind.
Claiming that "The Wii is interesting, but in terms of functions, it's a machine with past concepts." is the most retarded thing I've ever heard from a game developer, especially when his comparison is based on the idea that insanely overpriced consoles with better graphics than the last generation aren't "past concepts", despite the fact that this is what the industry has been doing since its inception.
For the sake of these guys, I'd pray that no one remembers dumbass comments like these when the PS3 crashes and burns. If I were Iwata, I'd be writing this sh*t down just so I could read it back to Konami when they come looking for a Wii dev kit.
I'd let them develop for it, but not without some hazing first.
