Ok, again, I ask, why does it matter if PS3 has Blu-Ray? If that format folds under, you will have what? A game console! (if it doesn't you'll still have a game console, but you'll be able to play some movies that are Blu-Ray format) If you think that because Sony is a part of the Blu-Ray camp and that means it will be the format that becomes the only HD format, then I'd ask that you research other Sony ventures into "future" formats, etc... You'll find that very few ever take off--if any. Of course, Sony has done very well with the Playstation family (I, II, and PSP), and I still see several movies in their format for PSP at my local wal-mart. However, this doesn't mean Blu-Ray will be a widely accepted format.
Now, if say a year from now, when or if Blu-Ray becomes the only HD format, and Sony decided to add a Blu-Ray drive to their consoles, I wouldn't see a problem with that. But now, with the future of Blu-Ray being so unknown, PS3 having a Blu-Ray drive means nothing. Because it could become a waste of money, space, and time.
