GT5P sold 5mi, i could bet my sister it will sell at least 12mi, which Halo: Reach will not come close, SMG2 maybe...

Halo Reach!!!

I have complete faith in Super Mario Galaxy 2.

60$ halo dlc sold 5mil, i could bet my sister reach will sell at least 12mil, which GT5 will not come close, SMG2 maybe...

Anyway... halo reach will probably sell the most. GT5 might have a chance of outselling it in 3 years, with most of its copies sold for 30$ or under, so halo reach will be more profitable for sure as well. SMG2 could potentially outsell both and since nintendo games never go on sale until a sequal, have the highest profit as well, but my bet is halo reach. With GT5 and SMG tied while the games' sales are still relivent. 

Well, many were in doubt of NSMB outselling the 360 version of COD:MW2 and in the time frame it did, and look what happened.....never underestimate the power of a mario game when properly marketed !

SMG > Reach = GT5.

GT and Halo will have a fight, Mario though is an undying beast that can still occupy top 10 chart for 3 years straight down, his legs are giant and he would never go out of style.

So no matter what u harcore think, shoot shoot shoot will never sell as gd as Mario the KING, cause he rules forever

About profitability i bought my copy of halo 3 for 24 pounds(release price was 40 pounds) about month and a half after release.

OT,my bet is smg.

I'm not entirely sure why I chose super mario galaxy 2 XD. I guess that the marketing it's getting for Europe and it being a sequel to an amazing game.... oh and being a mario game ^_^... will give it really amazing sales.

I have no doubt that GT5 will sell the most LTD. GT5 is the first GT in it's gen, it's been in development for so long, it has more content and features than ever, it's the best looking console game with the most content. And every main GT game sold over 10m safe. More likely around 13m is the average.

Halo 3 sold almost 11 mil, but it was hyped as the second comming of Christ, first Halo in the HD gen and the franchise wasn't beeing milked like it's now. No other Halo than the 3rd sold close to 10 mil, while GT games all sold over that mark.

SMG2 will not outsell the first one, the first SMG was a console selling, super innovative and original game, which sold a lot (8.6 mil) but nowhere near NSMBWii, which is in my eyes just above average game (almost double of SMG sales in 1/10 of it's time). So I can't see a reason, why SMG1.5 should sell more than the first (even though I wish it did, as SMG is the best Wii game bar none).
