Considering the very low prices, with one translating to $1, and if they can integrate the online leaderboards and such as the plan seems to be to good effect, I could see a good many purchases impulse and otherwise since the games don't appear to be slapped together.
I've no HDTV or 360 though...so surely do I hope for a PC version down the line. If they can find a good groove I see no reason it couldn't make it to Impulse, Steam, and so on.
