I think they'll crack 300k next month, but in the low end, like 310-ish. I mean, at $299, there's basically no reason to buy any other blu-ray player, so I think they'll sop up a lot of people who were in the market for one of those.
I hate to make the value argument, because it really sucked for a while when the thing was super expensive, but man, $299 for a super nice upscaling DVD player + a good blu-ray player + streaming media hub (and oh yeah ps3 game player) is a pretty hot deal.
but they'll still get out sold by both MS and Nintendo. I know people say that everyone who wants ODST already has a 360, but the bandwagon effect is huge with all things Halo.
