Some things I found interesting:
-----------

The PS3 version of Rage might indeed be the better version, but Carmack isn't thrilled with that. He feels the 360 is the better platform, and people won't realize that they (id) had to work twice as hard to get the PS3 version to be as good as it should be. Because of the disc issue, the PS3 version may end up being the better version and people will likely think the PS3 is the better machine, which is a view that Carmack disagrees with.

Microsoft discourages multi-disc games, and charges an additional royalty for additional discs on top of the basic media fees. This can discourage developers from shipping multi-disc 360 games to have competitive data amounts with Blu-Ray.

Carmack views Blu-Ray as the only real advantage the PS3 has over the 360.

RSX < Xenos (the 360's GPU). Some of that is because RSX is decended from PC hardware "with half its bandwidth cut off."

Given all the time you want, Cell can be better than Xenon. Otherwise, Xenon much easier to work with when time is an issue. Roughly equivalent. Cell (not including the SPE's) is roughly equal to a single core of Xenon. The SPE's and the two other Xenon cores are where things are more interesting.

The PS3's partitioned memory is a bit of pain, and their "system stuff" uses more resources than the 360's. "So memory is much more painful on the PS3."

The PS3 held up the release of Quake Wars, partly because its version was "lagging behind," but also because Sony won't let you release a game on another platform first without enhancing the PS3 version. Hence the 360 version was held back so they could be released at the same time ("political vendor stuff").

Quake Wars was a good lesson on how not to do things for id, and they're taking what they learned to make Rage work out better.

I like Carmack because he call things as he sees them. On top of that he's a big believer in Open Source - to the point where id releases their old graphics engines as open source! Openess is good - I remember reading once where he found some Linux drivers, found an error, fixed it, and uploaded the revised driver for everyone to use and enjoy. Seriously - the guy really gives back in a way I'd love to see more people and companies emulate.

At anyrate, his talk isn't a win for fanboys of either side, since he pretty much has issues with both the PS3 and 360. A pro for a system has a counter-balancing con with it. For those of us more interested in the industry, how things work, etc., this interview is just plain'ol interesting, I think.
