Why is anyone thinking that 1m is realistic? The Conduit may be hyped online, but not a single offline gamer I've talked to has heard of it. And these are the people that buy an FPS every week. The Wii base won't have heard of it either.
Commercial success: Probably 500k @ $5 per copy to the dev? That would be $2.5 million revenue and would pay each of their ~130 staff full-time + costs for two years, which is probably how long it took to make seeing as they were releasing other profitable games in parallel.
lol, it won't do 200k lifetime. First week sales of 75k would be on track for that. Won't stop me buying it though.
