The biggest hurdle that the PS3 will have to overcome.

crappy ports are only a launch problem.

 

That's a bit of a naive statement. 'Crappy ports' will, I suspect, be a feature of PS3 games for a couple of years at least - until it surpasses or comes close to the 360s userbase that is. In the mean time developers will look to maximise their potential profits and reduce development costs with cross-platform games.

I predict that in the end the PS3 will win out over the 360 due to the power of the brand and the fact that it will shift units in all 3 territories. I also predict that it will be quite some time before we see many games that fully exploit the platform's potential.
