I'm fine with no backwards compatibility. I'll just keep my PS3 just like I kept my PS2. Last time they tried to release a system with backwards compatibility, it cost $600. If sacrificing BC at launch is what it takes to keep the launch price down, then I'm all for that. Sony doesn't need a crappy launch price hurting sales like last time. I'm more interested in seeing how the PS3 streaming stuff will work. Save files aren't compatible, apparently, and it seems unlikely that you could import your PS3 disc library into streaming form. Like how would you be able to do that without being able to abuse the system? I'm guessing it'll work like PS2 Classics or something. Apparently PSN games won't be compatible either, which I guess makes sense. The PSN games are something that, in theory, should be free when it comes to streaming though, right? Because they're already tied to your account unlike disc games.
I read some more stuff about the controller. Apparently the touchpad can be “clicked”. Not sure how that works, but that's cool. It's always nice to have a little physical feedback. Rubber grips are cool. You can charge the controller when the system's off or on. And apparently that Options button is the merging of Start and Select. I wonder how that'll work. But at least the pause button's still a physical button.
