3.1 seem's like it'll be coming out within the next week or two. So I've been trying to come up with a new spec. I like frost but blood seems to be really good now. I've never really been a huge fan of unholy. I'm not really a huge fan of Bone Shield is the main reason.
Frost seem's it'll be really good at handling trash mob's because of Unbreakable being able to handle large amount's mob's while taking controllable damage. Threat will just as good, if not better for frost now.
Blood seem's to be really good for progression raid's, because of Mark of Blood, Vampiric Blood, and Will of the Necropolis. Threat for blood should alot better now, even surpassing frost on single target mob's.
These are the two spec's I've been thinking of using. I haven't decided on glyph's yet. Quite a few really good one's for major glyph's. The minor one's will be those 3 though.

Some talent mentions:
Scent of Blood - with the change to Blessing of Sanctuary, rp generation will be much harder now. This talent seem's decent enough to get.
Black Ice - effects frost and shadow damage. I expect it to be staple talent for all tank spec's now.
Lichborne - was a good tank talent. Now it's purely for pvp now and to avoid for tanking.
Improved Frost Presence - 2% damage mitigation. Not alot, but that's 2% more than blood or unholy.
Improved Death Strike - I plan for this to be my new FU dump. Will see how it does threat wise.
Will of the Necropolis - This one got slightly nerfed but still fairly good. The cooldown on it was added in 3.1.
Blood Gorged - The armor penetration will be good for blood tanking. Previously blood relied on warrior's putting up sunder armor for blood to produce similiar tps to that of a frost tank.
Epidemic - Since our dot's are 15 second's now, this one doesn't seem important enough anymore. With 18 second's, currently my rotation has room for mistake's. I usually have 1-2 second's where my rune's are on cooldown.
