I typically don't care much for debates of this sort, but this is one I'd really like to see. Morriston has written the most forceful critcisms of the argument. So, if Craig can refrain from rhetoric, showmanship, and debate tricks just this once, perhaps some new light will be shed on the argument. I'm not holding my breath, though. In any case, I trust that this isn't an attempt on Craig's part to make an end-run around having to give a rigorous response to Morriston's criticisms where it counts (viz., in the standard peer-reviewed journals).
If anyone gets or finds an audio or video recording -- or at least a transcript -- of the debate, I'd be grateful to get a link to it.

SECOND UPDATE: Well, it's been over two years, and still no sign of a link to the debate on the ol' interwebs. However, I've received word that the debate with Morriston was videotaped. Meanwhile, a video series of the complete debate of the Craig/Carrier debate is already online, and yet it occurred after the debate with Morriston. I trust that Craig will ensure that the debate with the person who has developed the most substantial published and widely anthologized criticisms of the kalam argument see the light of day (the most forceful of which are not, to my knowledge, addressed -- or even cited -- in any of Craig's published work, despite those criticisms being published about a decade ago).
UPDATE: Andrew Moon (Prosblogion) just returned from the debate, and offers his thoughts on it, here.
 I have in mind here Morriston's criticisms of Craig's a priori arguments against the possibility and traversability of actual infinites. To his credit, Craig has addressed some of Morriston's other criticisms of the kalam argument (e.g., his criticisms of the causal premise, his inference to a personal cause, and his a posteriori arguments for a finite past). The problem is that there's good reason to think the argument's force ultimately hangs on the soundness of the a priori arguments for a finite past. So it's puzzling that Craig fails to discuss -- or even mention or cite -- Morriston's criticisms of these arguments.
