Except a beta is always close to the real deal. Only in alpha do things change a lot. Beta is more for bugfixes.
LBP2's beta for example was almost exactly like the retail version, only with some exploits removed, making some user-created beta levels (which weren't available on retail anyway) unplayable.
EDIT: Played the beta, not going to buy it. It's not a bad game, but it's actually just meh.
