are they serious?
The only way UMD can stay alive is if they used the Blu Ray technology to get 10gb of space on a UMD disk, with read/write function. If they ever did that, MS Duo would be at the 128gb or even 256gb stage by then.
UMD has always been a dead format, I remember buying 4 movies for £10 back in 2006, brand new, the guy who sold them to me said that I was the first person to buy any.... ANY! and this was around april 06 and the PSP came out in the UK back in september 05!?! The guy was giving them away in bundles to people buying the PSP.
Sony are shooting themselves in the foot, once again
