Ok, my Motorstorm and PS3 impressions...
With Motorstorm, the graphics are just great. Tons of detail, tons of cars on the "road", etc etc. Easily the best looking PS3 launch game. However, I did notice that there were a lot of jaggies. And the framerate was just not smooth at all. The videos made it look as smooth as PGR3, but for me, it was just choppy. Even with only a few cars on screen, the framerate varies as much as TDU. It's not as huge of a deal as I make it out to be, but I was surprised about it, and it didn't leave a good taste in my mouth. The crashes were awesome. But after a few times you just want to get back to racing like in Burnout Revenge.
The gameplay, well, it's okay. Maybe it was because I was physically standing up playing it, or that it seems like slow-mo, especially when you getting up to speed after a crash without using boost. Or maybe it's because of the controller and it's jacked up triggers. And that brings me to this rant.
The triggers aren't comfortable. After holding it down accelerating in Motorstorm, my right index finger hurt. Not to mention unless you keep your finger at the top of the trigger, your finger slips off it pretty easily. Maybe I need to glue it to the trigger. But then again, I shouldn't have to glue my finger to it because Sony didn't design it the way it should be designed. For the weight of the controller, it was light, but that's because a big metal piece keeping it in place, so I can't really make an accurate judgement about it. I wasn't a fan of the DS2 design in the first place, so I'll probably end up buying a 3rd party contoller.
Now, when I tried to exit the demo, I tried the common sense thing: press the PlayStation button in the middle of the controller. Well, nothing happened. I tried again. Nothing again. So, I hold it down for 5 seconds like if I were to shut down my 360, and finally a question asking me if I wanted to quit the demo popped up. I chose yes, and it brought me back to the XMB. I was expecting the XMB to pop-up right away when I pressed the PS button so I could go to the internet browser while playing a game, but that never happened. Ah well.
As for the console exterior itself, it's very beautiful, one of the most beautiful pieces of technology ever, IMO. Even if Sony can't produce a TV commercial, at least they can design game hardware very well.
Overall, the PS3 is nice and all, but there's no way in hell I'd spend $600 for it. Motorstorm is also nice, and when I get a PS3 many years down the road, I might pick it up, or it's sequel if it ever gets made (with hopefully a better framerate), I'd probably buy it. However, I have absolutely no desire to get one.
I'd rate the whole experience 6/10, maybe 7/10. If the PS3 was a lot cheaper (like $200 cheaper), then it'd be an 8/10 or possibly 9/10.
