This will be a beta to iron out the bugs, not for people to get a head-start over the people who didn't get in. Most people don't even equate beta with actually testing. For them its a chance to play the game before everyone else. It's impossible to catch every bug even if everyone was rigorously testing like they are supposed to but if people actually tested instead of treating it like early access to the game the bugs would be severely mitigated. Hell even though most will lie through their teeth I would be willing to bet that the majority are asking about beta just simply because they want to play 2.0 before anyone else.

Nothing bugs me more than people who get into beta and don't test and submit issues.
