Don’t forget that that thing is not complaint with the new BR interactive spec and no firmware upgrade can fix that. That means when discs start getting cool PIP commentaries like in “300” this player won’t support them (and you just know that LOTR is going to have an awesome one).

At least when you buy an HD-DVD player you know the disc compatibility is the same from the top to bottom of the product line.
(note: I should also mention that I work for HD-DVD, but that doesn’t make this any less true ;))
