OK, I will offer the other side of the coin...
I got my first Toshiba HD XA1 two days ago, it was unable to play HD DVD's but would regular disks, so the new one came today. Did I need it?? No. I also don't need the various universal/SACD/DVD-Audio players that seem to be in systems, and some on the breakfast table as I just redid both my main systems, but being a nerd, like the new stuff, so I bought one as soon as I saw Blazing Saddles was out in HD.
I hate to say it, but I will likely buy a Blu Ray player (The format I feel is better) once they come out too.
As far as Best Buy, my local BB took down the display as the players are backordered and they were getting so many questions about them they decided it was easier to wait to redisplay the player until more units came in.
Will one or both survive?? I don't know, but for the $700 this player costs, I plan to enjoy it while I can.
