I'm not going to lie: I don't like Natal at all.
As far as tech quirkiness goes, it does the job, but I could definitely see it being something that you do for a few minutes and then get tired of it. Maybe little kids will get more mileage out of it but even then, if this is planned to be a Wii killer, I don't think it is going to come close. I'm going to feel pretty awkward moving my body around to imitate a steering wheel. I also don't see soccer moms and grandmas buying this en masse like the Wii.
Metal Gear Solid game will be multiplatform but that is another huge franchise that was once Sony exclusive (I'm not going to count the lol worthy Twin Snakes or the forgettable MGS2 port on Xbox), that franchise where fanboys were claiming that 360 sales would grind to a halt because the PS3 + MGS was the real deal. The only two big things Sony has that won't go to the 360 are Gran Turismo and God of War. How the mighty have fallen.
Forza 3 IMO was the real surprise. It has come a long way since the 2nd. I don't like the idea of buying games at full price but this might be an exception. I hope GT5 is there in top form tomorrow because otherwise, people are going to start dogging it.
