Don't be daft
The reason why developers showcase there games on the PS3 and Xbox 360 is because they want to get the best visuals , physics and game play possible and the Wii simply doesn't cut it.
Assassins creed with cut down graphics and wii remote sure would be a good game but with the graphics cut down how will that effect the end game play experience and product?
Dont get me wrong I have played some incredible games on the Wii mainly all 1st party efforts Mario , Zelda , Prime 3 , Resi evil4
Now building on the foundation that Prime has why hasn't a developer yet taken the controller layout and bought us a new FPS?
I thought Prime3 was a incredible achievement for Retro infact i'm going to play it in a second lol I mean even goldeneye with updated visuals and this control scheme would be awesome
The thing that concerns me the most is when developers begin to get really comfortable with the development process of the PS3 a few years into it's life
the games hitting the shelves then will look incredible and the Wii will pale in comparison.
Nintendo need to embrace HD pretty soon that's why I think the wii will be shelved in about 2010 to make room for the natural progression that would be the Wii2.
