Filed under: CES, HDTVWe just got an email which stated that the HD DVD group is canceling its CES press conference; tail severely between legs over today's explosive news that Warner -- the last "undecided" studio -- was going to the other side and doing Blu-ray discs exclusively. We're not sure if that's because the HD DVD group was in 11th hour negotiations with Warner or what, but the mood at that camp has to be beyond somber right now, so it's pretty hard to thump the tub when you've just been dealt a hard losing hand.
