This is an interesting idea, and it should make beta players feel like they still got something out of participating in the beta (other than actually playing the game for months and helping shape it). ReRunners has plenty of promise in part because it's a really good platformer and in part because of the multiplayer element that makes it a great game for players who enjoy competition. So, if you're one of the beta players, enjoy the early release version, and as for the others, not too long to wait now.
