If Castiel can be brought back for choosing the right path, why not Gabriel, I say.

Spoilers 3: First Mutant Enemy, Now the World
[NAFDA] Spoilers for any and all currently running TV shows. All hardcore spoilage, all the time. No white font.
Here, here!
Or is it, hear, hear!
In any case - bring on Gabriel!!
Hmmm. Gabriel's powerful enough to travel through time, so theoretically he could show up again and be his pre-"Hammer of the Gods" self skipping forward a year or more.
Hell, why not? Shouldn't be that difficult to write Gabriel back in given all the plot devices they have available.
According to Fred Lehne, he will be returning as Azazel in Season 6. OMG!
Also looks like Corin Nemec will be in a recurring role as Sam and Dean's cousin.
Awesome, but, how?
With Mitch Pileggi returning too, it sounds like they might have some sort of time travel arc?
Huh. I mean I like those guys, but...
It was suggested that it may be flashbacks for gramps and Azazel.
A bit of spoilery interview with Eric Kripke for Season 6.
Also from Ausiello: Season 6 will revolve around Dean’s new life as loving husband to Lisa and doting father to Ben. I keed, I keed. Despite the domestic situation Dean found himself in at the end of last season, exec producer Eric Kripke assures me that Supernatural will continue to be about the Winchester brothers “on the road together.” That said, Kripke confirms that “Dean’s situation creates all sorts of angst and conflict. The question [we'll be] exploring is, How can you be a hunter when there are actually people that you care about? I think we will mine it for all of the emotional angst and conflict that we can. But [Lisa] is not — nor is anyone — going to be riding in the backseat of the Impala with Sam or Dean.”
