I think that Dean will say yes to Michael. And I really hope he does. That would be awesome!!!

I hope so, too. Michael is kick-ass - loved his entrance in TSRTS - and I want to see Jensen rock it as a powerful archangel who takes crap from absolutely nobody.

Besides, the Lucifer-Sam connection got multiple nods already, right down to Jared getting to play Lucifer. Now, I want the same for Dean and Michael.
