We'll have to watch over the next few days to see how the stock numbers move. But the ranking doesn't seem to have moved all that much in the last couple of days. The price for the HD-A2 is $357 right now, so that might have more to do with the increased sales over the last 3-4 days. Although I don't know what the price was last week.
I'm hoping the price drops a bit more. When it hits $299 I'll likely pickup another HD-DVD player. Or when I can get an A20 around $400.
