I read a lot of comments here and elsewhere about the PS3 not having good games.
If you believe that, you aren't paying attention to what's out there.
MS may have more games available and may be selling more games, but that's because Americans have a never ending appetite for first person shooters, Madden, and Big Macs. Games like Uncharted, LittleBIGPlanet, and Valkyrie Chronicles are real works of art and represent some of the best games from this generation, but nobody's buying them because they believe the PS3 "has no good games yet" thanks to shit articles from the likes of CNN Money.
Anyway, the PS3 is no longer the only game in town for a Blu-ray player in its price range, so in that respect, its effect on the success of Blu-ray is tapped. However, many current PS3 owners helped contribute to the outstanding Blu-ray software sales this holiday season and will continue to do so through the coming years, so from that angle, the PS3 paid off for Sony.
At this point, Blu-ray hardware manufacturers have moved so many units that Blu-ray's future as a format looks very bright. I don't see it ending up like laserdisc at all.
