HD-DVD a healthy lead in Europe? Wow, I'm impressed. The first drive was released, what, 19 December 2006 - hardly a month ago? I wouldn't be surprised if as many PS3s have been imported into Europe as HD-DVDs sold in retail.
Certainly, although I've seen (expensive) Blu-Ray players in stores here in the Netherlands, I haven't seen any HD DVD players yet. So maybe Europe means the UK only?
