Theck has already posted his current Cataclysm Matlab breakdowns over at Maintankadin. While more input is always better, it's fairly safe to say that his work is at the very minimum an excellent jumping-off point.

That's definitely a good starting point for single-target tanking. Two things I see missing are a discussion of AoE tanking in general, and the threat component of WoG. While it'd be nice to be able to say replace CS with HotR and ShoR with Inq and call it a day, AoE tanking's simply not been addressed yet.
If the protection thread is to be believed, the threat from WoG is nothing to scoff at for AoE tanking, especially at 80 while we're still sans Inquisition.
