If this game is at least half decent and gets advertising I could see it doing very well, I just hope they aren't sending it out to pasture.
Someone made the point that it might sell 500K without advertising and not alot more even if they broke out all the advertising stops, which is possibly true but how about going all out and trying to create that breakout new IP which will continue to sell better over several subsequent iterations. We've already had a couple of great new core franchises this gen in Uncharted and Gears of War but the industry needs to keep trying to create these popular new IPs or all we are going to be playing 5 years from now is COD8, U4, FIFA ad nauseum and MKZii.
