They're milking the market for early adopters. Their price will drop eventually, too. At some point, the MBP will come straight from Apple with either a Blu-ray or HD DVD drive pre-installed, even if only as a CTO option (for less than $1000 extra).
Either way, I wish SOMEONE would go ahead and win this format war already. At the outset, I thought surely Blu-ray would be quickly victorious, what with equal definition and double the storage capacity---but this has gone on way too long now.
