If I were a bookie, I would give the following odds for the console with most million sellers at the end:

360 - 3:2
Wii - 2:1
PS3 - 3:1

Handhelds are known for having low attach rates and software sales given their userbases. The DS is loosening the trend, but it's still unlikely to break the trend.

I'm thinking it will be:
1. Wii
2. Xbox 360
3. PS3

Wii

I think that it will be a close call between the X360 and Wii. The X360 will come out on top though. The userbase of the wii will be gynormous but the games will be diversive, and the amount massive. There will be a lot of spread on the Wii which will make it the most profitable and most liked to develop for, but the 360 will have the most concentrated bunch.
Most of MS' titles are multi-plat with the PS3 though but as we have seen with GTA4, the X360 will most likely come out on top.

that makes no sense, if teh 360 has a small bunch what you will see is a few games hiting 5-6 mil not a lot of games getting above a mil

where as by your own reasoning the wii will have alot hit 1-2 mil and not very many hiting more 3 mil....so the wii will still end up with more million sellers

Wow how the high days of SONY are over. With the PS2 there was nothing close to it. Now SONY will be in the rear end looking ahead of the Wii and 360. I believe 360 will be first due to the fact that it has more exclusives than the Wii and has a better attach rate. PS3 will be dead last and far away from the 360 and Wii due to the fact that the attach rates are generally low and it has a small install base and its good exclusives barely hit a million anyway.

Lol. Keep telling urself that SONY fanboy.

Nintendo can't make that much million sellers.

... if you catch my drift.

No the wii wont, I think the 360 will end up with the most.

Also the reason why the PS3 should have the least is because of its time on the market and its low install base compared to the wii. If the ps3 manages to take the lead though I think it has a chance.
