i think you are way off on this. i would be willing to bet that over 60 percent of the ps3s sold on launch day went on ebay. i think the ones who kept them are the hardcore gamers who want it for games and not so much for blue ray. i don't think people camped out three days to get a blue ray player.
i don't think the people wanting blue ray are spending over a thousand dollars on ebay for a blueray player. i think the ones are that are selling are for video game use and not blueray.
I've bought more BD than games. 8- 2
