One of the reasons they might not be releasing a beta with potential brick code is the fact that, as mentioned earlier, most of the users are probably kids. Agreeing to the ToS of "we are not responsible blah blah blah" as a child means nil in the U.S. Minors bear little to nil responsibility for accepting legal agreements and can be easily freed from those "obligations". So if they DID release brick code, some brat could say "I didn't know what I was agreeing to" and regardless of if the courts took it seriously or not, it could still potentially be a hassle for them. That's why I think eliminating any potential for that and taking their time for this polished release works in everyone's favor. No bricked consoles, no risk for them or anyone else... unless you really don't know what you're doing or intentionally try to brick it for whatever reason. That sort of thing is on the head of the user at that point because they were they ones who did it, child or no.
