Nice find. I'm not going to say I'm surprised that BR has sold more as much as how quick that was. That report you linked says since both came out, meaning that's factoring in HD's head start. This isn't bragging or anything, but that's honestly not good news for HD to have been out few extra months and to be overtaken so early. It's like getting a 30 second head start in a mile run and you being passed up before 1/4 the race is over, I mean sure there's still time but your headstart ending up meaning crap.
Again, sooner this format war is over the better. Less ppl end up buying whichever loses, and sales of the winner should go up when ppl know for sure their not buying into a format that'll be gone in a years time.
