UPDATE: Gamedaily has the
goods.A sample:
"SJ(Simon Jeffery, President of Sega of America):The game itself is absolutely being built as a joint venture between Nintendo and Sega. The predominant game development is being done by Sega's sports team and with a fair amount of help from outside companies, and also from Nintendo themselves. Mr. Miyamoto is very heavily involved in the overall direction of the game, the gameplay mechanics, at an executive producer sort of level. He's looking at every milestone, he's giving up suggestions and directions, and Perrin Kaplan actually told us yesterday that his involvement is way more than a lot of normal Nintendo games. And his blessing is really quite a landmark for a game like this that's being built outside of Nintendo itself."
There you have it people. Unless Miyamoto takes a dive, it should be at the very least, technically competent.
