I feel the same way. I still through HVD technology was a few years down the road. If it comes out at the same time as two other new formats then it could very easily be a 3-way war of the disc, all of which are going after the DVD.
On face value, a 200GB disc really offers a lot of value. 10.3 channel audio at 192khz per channel plus 40mbit+ mpeg 4 video at 1920x1080p/24 would just blow a lot of people away.
Probably all come down to cost though and who can deliver on their promises.
