There's still a lot left, people can still make great games, there is still that potential.
Technically we've pushed it where we want to, as far as games are concerned there are still plenty more to be made, it's just a question of how much support a developer is going to give it.
I agree, people dismiss the platform but really it comes down to the games on the format, I think that the platform rocks; it has potential. I think that the PSP2 and PSPhone will really depend on the games both 1st party and 3rd. I terms of GOW:GoS looks amazing and I can't wait to get it!
