Games should be developed on the ps3.

I think games Should now be developed on the ps3 It would benifit both the xbox 360 and the ps3 if it did and this is why.
Okay sofar this is how "Most" games are developed. First they are made on the xbox 360 and then ported to the Ps3 Why they do this i have no idea but it should be the other way around beacuse if they were developed on the ps3 the Devs would use more space on the blu-ray disc and then if it was more then the DVD-9(Disc the xbox 360 uses witch is 8gbs dual layerd) they would put the game on muliti disc and not compress it and have the best graphics possible on the xbox 360.But the devs right now dont want to take the time to learn how to develop on the ps3 so they just stick to the 360.
So right now it is a fair statement to say that the Xbox 360 is holding back the ps3 a little
