I'd say 1 million is a good target for life time sales.
I'm not sure how well indigo prophecy (or farenheit depending on where you live) did, but I would imagine it didn't sell huge volumes.
I think CGI-Quality is doing wonders for hyping this game here, I seriously thought it'd be a piece of crap (despite the developer) who's only talking point was graphics (something that was a characteristic for many PS3 games before Uncharted launched). But now, I've got pretty high hopes for this game.
