Most people don't even have a 5.1 set attached to their TV.

This fails right here: by your definition, absolutely no Wii game has ever looked good?  Of course, most of the cash-ins have been crap, but come on!  Mario Galaxy doesn't look good?  Medal of Honour doesn't look good?  The Rayman games don't look good?  SSX doesn't look good?  Zack and Wiki doesn't look good?  Umbrella Chronicles and RE4 don't look good?

No one is implying that Wii will ever be able to pull off more realistic graphics than PS360.  They are saying that, MAYBE, by the VERY END OF ITS' LIFE, some of the most talented developers, putting lots of time into optimization, might be able to make it do what some devs are doing right now on the PS360 without optimization.  Meanwhile, at that time the difference in PS360 graphics then and now will be like the difference between PS2 circa 2000 and PS2 circa God of War.

  And that sad since this was on of the best sounding game in DD5.1 I've played.

 Still as someone noted they already took a shortcut with PS3/Xbox360 by not having it in true HD (720p) so maybe with more short cuts it may be possible later (in 480p) to make games for Wii close to CoD4. 

Why would they do that? CoD4 and AC sold 4,5 mln. and 4 mln. each. And these games are only around 6 week on the market. + We all know, that 3rd party games don`t sell very good on nintendo consoles.

IF you want graphics, get HD console. IF you want HD graphics and motion control, wait for Wii HD or till Sony/M$ will figure something.

 OR, as a Wii owner, you could want graphics and be perfectly happy with Metroid Prime 3 and Mario Galaxy.

BTW, people need to cut out with "3rd parties don't sell on Nintendo systems" when the Wii has about 200% better 3rd party sales than PS3 has and probably ever will. 

Wii cant even achieve half life 2 graphics let alone cod4..

I've seen that the sentiment around, even in Wii fans themselves, is that no Wii game can have good graphics. But obviously they can, from both the technological and artistic level. It's totally different that most third parties are cheap bastards and they port directly an engine from the PS2 era or that they don't even try to make a good looking game (I'm looking at you Konami)

"OR, as a Wii owner, you could want graphics and be perfectly happy with Metroid Prime 3 and Mario Galaxy."

Bingo which is why I doubt developers are going to waste too much time on improving Wii graphics so you probably won't see too much better graphics than your examples. Wii strong point is it's controller not it's hardware/GPU.

I did read the whole thing, she said that the Wii only lacks the horsepower to be as capable as the other two, which is perfectly reasonable.  But the first sentence is just incorrect.

"Sorry, but if anyone says "this game graphics look good", then by default it can't be done by the Wii. Simple logic."

I don't even understand why this was said, as it contradicts everything else she said.

EDIT: Sorry, Fazz, I was in the middle of typing this post when you posted your last one.  I see what you are saying now, and I agree with it.
