The best thing, for long time gamers that is, as more expansion occurs the higher production value can get and the cheaper games can get. If there is more of a userbase then more cost efficient things can be released. It's why DVDs are so low in price yet have higher production values than games. Can you imagine buying a game like Halo 4 for $30. It's possible if the market keeps expanding. Apart of that expansion will be becoming more cost-efficient because its the only way to do it which means cheaper games.
