I honestly don't think that its going to matter come expansion what tanking class you are. I've read a number of blue posts that says they will still all have unique abilities, but they are leveling the playing field for all tanks.

Warriors, Druids, and DKs will have equal AoE abilities to Consecrate
Paladins, Druids, and DKs will have oh shit buttons equal to Last Stand
Druids armor on items is getting greatly reduced to make their armor more in line with the other tanks.

They don't want to make 1 tank required.. such as , why use anything else if you have a prot Paladin for Hyjal. Or why use anything but a druid on a hard hitting mob like Tidewalker.

Be interesting to see how they handle it, but what I've heard that I do not agree with is how a DK doesn't have to choose a specific talent tree to be a tank. They can cherry pick from any of the trees and do just fine as a tank which baffles me. So their Blood line, tanks as well as Frost or Unholy? doesn't matter? Just weird... :thumbdown:
