It was just a question man, I dont know why you wouldn't have a version that gets all future updates especially at $60 or $100 that's the price of a finished game.
However, if you allowed the game to be updated for people who already purchased it, they'd be more willing to buy it. As is, people pay dozens of bucks for incomplete, intermediary versions.
Naturally, you should incorporate that they don't get the benefits that they didn't pay for.
