I think he's wrong - I just don't think someone would consider a PS3 for BluRay. Quite simply, it's not the best BluRay player around anymore. It was quite a few years ago when all BluRay devices were within ~$50-$100, but now you can snag a BR player for under $100.
One of the failings has always been the lack of a bundled remote. For the novice users, fumbling around with a PS3 controller is a little much. Having to buy it separately kind of added an annoyance to some. To note, not bundling a HDMI cable in this day and age is almost criminal too. I know they want you to buy the overpriced ones in the store, but come on @ the PS3... I mean they don't even provide HD capable cables with it.
The one thing the Xbox 360 still has a head on, is backwards compatibility. Their latest console still plays all the other Xbox games the launch console did. To note, they aren't adapting more to be compatible anymore. But, with the PS3, you have just PS1 games. Unless you have an older console, they dropped PS2 entirely. I believe that greatly slowed their momentum. It is pretty clear as to why now. As you can see their new HD transfers of PS2 to PS3 games. Which from what I can tell, seems restricted so far to Sony games. Kind of seems pretty clear now to what their real motive for dropping the backward compatibility was.
We will see if the price drop helps sales any, though I am expecting there to be a 360 price drop in time for Christmas.
What I am wondering is if the next gen will stick with traditional hard drives, or move to SSDs. Only time will tell I suppose, certainly depending on their price point at the time
