WIthout a doubt the architecture is much more modern, however Nintendo went down a green route rather then a performance route. 
For example, the 360 can reach about 170W at full load. The Wii U will onyl ever use 75W of power, and let's not forget that it's generating graphics for two screens. That is certainly impressive that they've shaven near enough 100W off the 360 and are doing more. 

However, that also means that they aren't really going to be able to noticeably out perform the 360 as the power it is using isn't going to be able to give it a push much beyond the 360. If the next xbox or playstation use ~200W or even more, then they could very well be a generational leap over the Wii U as they could dedicate the entire power draw of the wii u to a gpu alone. 

Yeah, I agree they should do both things, but as far as I know it's not the "Nintendo way"... And I agree that they should open more in house studios, but I read something Miyamoto said that there's a reason why they don't do it. They don't want to risk lowering their quality by flooding their studios with new people; That would mean learning all the new folks the way of Nintendo, and that would take up a lot of Miyamoto's time, when his time is already limited as it is...

What they really should do is to buy studios, and create "2nd parties" in the same way they already ahve got Monolith and/or Retro.

You're really talking over my head right now; you're probably right :p Visit superchunks Next gen vs next gen thread!! :p

The Wii U is doing fine and by the looks of things will continue to do fine. Pikmin 3, Wonderful 101, Bayonetta 2, Lego City Undercover, Rayman Legends, Monster Hunter 3 Ultimate, Wiifit... all exclusive titles launching in the next 3 to 4 months. And Pikmin 3 looks amazing period. 3rd party support so far is good with 3 very high profile titles appearing at launch ME3, AC3, Blops2. Along with an established powerhouse 1st party title in Mario. The Wii U has perhaps the most varied launch in history with high rated RPG's, fps, action/adventure, survival horror, fighting, and sports. What more could you ask for as a gamer? Not to exclude full backwards compatibility with the Wii, which makes Wii U the only console that you can play three of the best RPGs of the year on with Xenoblade, Last Story, and Mass Effect 3. Sure if you try to find fault with the console you will, but taking looking at it without the fanboy goggles on you see its an amazing value for the price and is looking to have a bright future.

Theres plenty of Wii U's where I live.

I think it's a good start, but it is quite worrying to see them on shelves everywhere.

My local gamestop has them stacked in front of the register counters. And they're literally stacked. They'll sell more during the holidays.

oh wait it is the holidays.

It will be a slow burn as many of you already said. There's a lot of potential that isn't even taken advantage of yet.

I was out shopping tonight, went to three stores and I saw one basic. It's funny how Nintendo ships all the wii u consoles to areas where the haters live and doesn't ship enough to the areas where the nintendo fanboys live.

Selling 88% of what the Wii did in the same time frame is pretty impressive, but the real challenge will begin after the holidays.

When the dust settles, I think I can say that the top five best-selling launch titles can be considered, at the least, a moderate success.

I think that the Wii U is doing quite well despite there being two other consoles on the market full of great, CHEAP games. I'm sure that it will dominate in Japan because Nintendo actually releases good games out there and Europe should be fine after Nintendo fixes the online M rated content block in the eShop. After the holidays roll on by things should start stabilizing as well, and we'll start seeing if Nintendo will keep its current momentum. Games like Rayman, Bayonetta, Pikmin 3, Monster Hunter 3 Ultimate, and Wonderful 101, should really help push systems after the holidays. Nintendo just needs to focus on future third-party games and announce some nice exclusives before or by e3. I honestly think that it was a smart move in delaying some of these titles and spreading them accross month by month, it helps keep things freash...
