Since this game will have a separate PS3 release, I don't think it has a time limit yet. If PS3 turns out to be good and have good reviews, people will start looking this way. If PS3 version doesn't deliver, then it has limited time.
This game is very WIP even though it is retail already.
3DS 'flopped' because there isn't many games on it yet and a console isn't worth much without games. Especially a handheld. It might turn out to be a success once more games are released.
