Yeah, but prices will soon drop as production starts. They'll both, (even Blu-Ray) drop to standard DVD player sort of prices in about 2-3 years.
I'm more supported over Blu-ray if they get the protection of the disks sorted out.
I've heard they are taking off the protective cover though, so I'm less happy about that. Having a protective casing like Mini-Disk would help these disks alot! Though that would cost more, but the actual CD's would last longer, with NO scratches!!!
50GB though for Dual Layer would be alot more supported by me than only 15GB on HD-DVD is it? I could fit my entire drive on one Blu-Ray disk for backup!
