As it comes out in spring. It will have most of the year to get the sales. So 25 million should be very much possible.

25mil seems kind of out there. GTAIV has gotten to 20mil with amazing legs for an hd title. Considering there hasn't been a grand theft auto in 4 years and there have been more sandbox games coming out over the past 2 years than ever, I think its a bit soon to be predicting call of duty level sales for GTAV.

I understand where you are coming from and you are probably right that the forecast is really optimistic. The increased sales is just taking the expanded console base into account compared to its last iteration. I think 15-20 million copies would still be the best and more conservation estimate of sales in first year. Also we don't when the pc version would be launching. So that makes 25 a bit hard i guess. 

I hope so. That would be a nice boost for Wii U and it will play smoother with the extra ram :)

No way. When it's released, PS3 and 360 will be closer to the end of their life cycles, and I highly doubt that it'll sell on Wii U.

Exactly where is this 25 million in one year prediction coming from? GTA IV is 4.5 years old. Even with phenomenal first week sales and great legs, it has only sold 19.95 million on PS360 to date.

No way at all. GTA IV is still a long way off that and released earlier in the system's life, and has had much longer to accumulate sales.

Impossible. I can see it selling 25m LT, but on the first year? Hell no. I believe that even CoD hasn't reached numbers like those on its first year.

It's not coming to Wii U.......

I think it's definitely possible.  It would need amazing marketing and word of mouth. Of course the game itself would need to be amazing as well. Lots of sites gave GTA IV a 10/10, how can GTA V top that?

You sure about that? It's quite possible it'll be ported to WiiU depending on sales of ports at the launch of the system; hence no announcement.

Same with PC, but obviously that's certain to come.

I think GTA V will end up coming to 360, PS3, Wii U, 720, and PS4. It will exceed 25 million in its lifetime, but definitely not in its first year.
