Obviously they will wipe out the ladders once retail hits, but does anyone know if the are reseting names/identifiers and achievements? I'd be pretty annoyed if they erased our stuff, especially since its practically the full multiplayer suite.
Of course, it's still beta. They will wipe everything, then when the game launches, everything starts fresh.
There doesn't need to be. They will wipe it, I don't know why you think they would carry it. Your supposed to be testing it, not playing it early.
This. They will wipe it, just as they have wiped all your achievements and ladders multiple time since day 1. What if you weren't in the beta,and started playing and all these people already had like 100 worth of achievements? Wouldn't your milk turn sour, and you wouldn't want to drink it? =)
There's been chat about an achievement for participating on the beta. But past that I don't think any will carry over.
There's nothing you can do about it. The beta is for testing, not so you can get a head start on achievements. Just be happy that we were lucky enough to play in the beta at all.
