Yeah, that is weird Ty.
Anyway, assuming the DVD Empire data is fairly representative of overall sales, it looks like PS3 isn't going to deliver the knockout blow anytime soon. The initial rush of PS3 sales look to be over, so I think it'll take a while (over a year?) for PS3 total sales growth to really outpace the growth of HD-DVD standalone sales (percentage-wise relative to today) and deliver that knockout punch.
Cheaper standalone players should be around before then. That should determine the winner of the war. $200 should be low enough to start stealing sales away from DVD players over $100.
