GTA IV being held back by 360?

[ckmlb]

I think we all know developing for any console has challenges, but the point of this article is that not all 360s having hard drives is a limitation, since the game company has to think of what to avoid doing to make it work with the hard driveless version. I never liked the idea of the core 360 and still think it's pointless to buy and not a good idea by Microsoft. I wish there was some kind of way of seeing how many of the 360s sold are premiums and how many are core version, because I am willing to bet the vast majority are premiums...
