Devilman is probably right about the PS3 though. It will be expensive, but aside from that it will be the first player with mass market appeal. That should solidly make sure Blu-ray wins in addition to the technical superiority (I hope).

Both HD-DVD and BD (Blu-ray disk) drives will be designed to work with already existing DVDs, so there's no probem there for the average customer. Whichever format becomes the most popular will have all movie companies releasing titles for. Star Trek and anything else will come to Blu-ray quickly if it wins the format war.
