I'd be very surprised if it doesn't sell 1.5 million copies.
There's a lot of hype for the game, which al but ensure decent pick up among the core groups. This will also ensure lots of retail exposure to the game. And FPS isn't a real hardcore genre, it has become quite approachable for more casual gamers over the years.
Plus I expect Sega to do a lot of marketing as well. You can't compare this with MoH: H2 (no hype, PS2/PSP port) and CoD:WaW (is more complete on other platforms) since this is an exclusive and seems to do everything right.
