I would agree here with jeff and say that it isn't worth holding on for blu-ray/hd-dvd. However, I've read a few interesting pieces lately which seems to suggest blu-ray/hd-dvd burning may not be as expensive as first thought.
The hd camp recently announced they'd be providing recordable hd at launch only for the blu-ray camp to announce the same days later. It took a while for dvd-r to become available to the mass public but this time round it's going to there at, or very soon after, launch. Due to the fierce competitivism between the formats it's entirely possible there will be a price war and that could reflect well for us as consumers.
Unless of course we blow our money on the losing formats product...
