I just realized that Nintendo will stay in first place for a long time

Casuals  The Expanded Audience will buy Wii U because of :
Mario Brothers Mii
Wii Fit 3
Mario Kart U (lol)  etc..etc..

A lot of the new Expanded audience are now interested in Wii products and as long as Nintendo offer them improved versions of these titles AND a Killer app that gets everyone talking it will be a success.

The Wii U doesn't have the same "WoW!!" factor that the wii did, but just like portal to Portal 2, I expect there to be improvements across the board that make the Wii U a must buy. I don't think it will be the wildfire that the Wii was but I expect it to sell well ( 65Million + )

With HD graphics and standard button controls + optional Motion controls + IR controls I expect the "hardcore" to be More likely to buy a FPS/Gory game on the Wii U then on the Wii which should push up the attach rate for the first 2 -3 years.

So : Lower Hardware sales, but increased Software.

The new controller is a complete unknown but I did get an interesting feeling seeing the golf ball being hit in WiiU Golf, if they can create that feeling for entire games, it might sell very well.

As another poster said - They showed a 2D mario game as an example, they have SEEN mario 2D far outsell mario 3D. They can't ignore that. Also MORE people bought mario 2D and Mario Kart then all the Hardware sales of GC showing that these games have reached new people (me Included) that will automatically boost the sales of Wii U far beyond the GC if not to the heights of the Wii.

The Wii is still selling well, if your right about the casuals not upgrading it might be that it will do a Ps2 - at least till Wii Fit 3/MK/Dance whatever etc comes out. If Nintendo doesn't support it some of the 3rd parties WILL as they won't ignore the 90 million consoles out there that no longer have to contend with Ninty for (new) game sales.

One thing that is very important is that they keep the Motion controls in Focus to a degree - I don't think anyone should believe they can't play Golf in a natural way now that there is a new controller with thumb sticks and the trailer did a good job of that (showing the new controller working with the Balance board and the wiimote+)  They will have to include a Wiimote+ and nunchuck in the Package of the WiiU or they will loose everything they gained this gen.

Due to the types of games they showed in the trailer I do not believe they have lost focus on the new or old audience -

Golf, Mario Bros Mii, Wii Fit, Chase Mii, battle Mii, Zelda.

Infact they did a completely different Trailer for 3rd party/Hardcore games.

This is very interesting - just think about that for a while. They are making a 2 tier system within one console.
