So my next system will probably be a Wii

[Shuri]

The wii is fun for about a month or so, and then you just stop caring. If you own a 360, dont bother getting one. The novelty wears off fast.

I own a Wii and have enjoyed it so far.  My only worry with the Wii would be third party development.  If you chart the last 2 generations of Nintendo third party support it would look like the following.

N64: Launch lineup was basically Mario 64 and no one cared for the first month because the game was so great. But basicaly non-existent third party.  Great second party.  Rare.  And many WWE fans claim the N64 games were among the best in the genre.

GameCube: Great lauch lineup.  Better support from Japanese devs, such as Capcom and Namco, but it fizzled as the PS2 ran away with the generation. 

Wii: Amazing buzz from e3 due to Wii Sports and interest from casuals, but lauch lineup was meh.  So far much of the third party development has not been the most ambitious.  Stand outs have been EA and Ubisoft, more due to support than quality,  Greater install base this time around should net better third party exclusives.  Only time will tell though.

My anticipated titles:

Metroid Prime 3
Nights 2
Super Smash Brothers Brawl
Super Mario Galaxy
Zack and Wiki
No More Heroes
Animal Crossing

no, that's not my assumption at all. in a genre that goes for full-on immersion by placing you directly into the character, detail is tantamount.

There is tons of detail in Prime... but nothing that exactly relies on tech, just more on being thought out. Like the rain trickling off the invisible platforms.

it's pretty fucking plain snobby (just not in a funny way) to think you need detail from polygons, textures, and shaders to get somebody immersed.  There's nothing that I see in games on next-gen systems that is impossible to do (and keep all the artistic quality) on Wii with Metroid Prime.
