Nintendo of America president, Reggie Fils-Aime has denied to Stephen Totilo that the reason games such as GTA IV and Assassin's Creed haven't made their way to Wii is a technological one. In Reggie's mind, if you do enough marketing, any game will sell.
He responds to the assertion that "technology was still a formidable obstacle" with the following:
"I think for those games, typically decisions are being made two years prior. And so the decisions two years ago were that those types of games would not be effective on the platform. But we've shown that that's just not the case. High-quality, effectively marketed against our installed base will sell, period end of story."
Maybe making a tiny adjustment to the technology might help? HD? "What that says is that simply the addition of HD capability will not be the next step for us", says Reggie.
