Yeah it's very optomistic for Halo 4 lol. I hope that doesn't come to bite me in the ass when Halo 4 comes out.

VGC doesn't have the best record with preorder numbers so I don't take them as concrete.  That guess is based on how it opened in Japan with some added for being a much talked about game because of the Rainfall stuff, though that could be countered by the people that imported it (like myself).  

I suck at predictions. The last prediction I made was spot on... only because Nintendo had trouble producing wii fit boards!

This is generally when Console generations start dieing off.

I'll guess

Wii - 10 Million
360 - 13 Million
PS3 - 14 million.

The economy somewhat fighting off your usual drops.

Hardware

- PS3: 15.4m
- Vita: 6.4m
- PS2: 1.6m
- PSP: 1.2m

- 3DS: 19.8m
- Wii: 8.5m
- DS: 6.1m
- WiiU: 4.9m

- 360: 15.1m

Software: (by the end of the year)

- Starhawk will sell 2.5m
- GTA V will outsell CoD9 on PS360
- The Last Guardian won't be released worldwide
- Mass Effect 3 will sell 5.0m on PS360
- Uncharted 3 will sell 2.0m

Going to assume you mean Uncharted Vita?

Hardware
Wii 7 million(Going by how fast it dropped this year and DS this year)
DS 5 million(Nintendo know how to kill hardware)
3DS 17 million (I'm going to assume their will be a redesign and a 2D mario released in the holiday)
PS3 13 million(I'm guessing it will start going down because it won't have a another price cut)
360 13 million (Guessing their will be a price cut since its last one was 08 also America will be up yoy)
Vita 9 million (Typical PSP numbers)
PSP 5 million (The decline continues!)

Ah wii U
Wii U 1.5 million(No way Nintendo will not release it in the Holiday season.)

Wii  10mill

Wii U 5mill

360 12mill

Ps3 13mill

3Ds 18mill

Ds 4mill

Vita 8mill

No you can predict whatever. Do you mean U2 will sell 2m IN 2012? your (by the end of the year) comment threw me off
