I would of offered already Take Two/Rockstar 1-2 billion dollars to make Grand Theft Auto 5 there exclusive launch title, the steep money would be because that game will sell like 20+ million units. I would Pay Activison another Billion dollars for an exclusive Call of Duty title.
Basically i would been handing big Wii money out to developers to get the hottest games on PS360 there next console exclusive.
If you were an PS360 gamer and you find out that GTA5 is only coming out on Nintendo's New console would you rush out and buy it?
If Nintendo is really aiming for the "HD" experience: they are going to need games; big games because no one is going to buy this for the port box waiting for nintendo to release there new games that use the tech, and no publisher is going to spend 20-40 million developing an Sku for there new console with an install base of 5 million.
Nintendo could pull an dream cast, screen on consoler, half step upgrade from PS360.
Of Course That's Just My Opinion, I Could Be Wrong
