Looks like Commander will not be enabled during the beta, which is a shame. That also means other features may not be fully implemented... these are the things I need to see before I buy BF4. I need to know VOIP is there on PC in the game (no external client) and it's functional. I need to know the new game modes are balanced. I'd love to see Commander in action... as it is, I'll play the beta, but that's the stuff that's going to get my $50 (or eventually $100, I guess, with Premium).
Also, Open Beta is going to be crazy, if it's anything like BF3 (and I'm guessing it'll be even bigger) you'll have hour waits to get into a server. Closed beta (1st-3rd) may be just as crazy.
