Gen 5 to get DW abilities at last

The other day, I mentioned the genies caught in the Dream Radar would have their Dream World abilities if returned to their regular forms. Today, Serebii updated further, saying that if you're playing on the Dream World with a game of Black 2 or White 2, generation 5 Pokémon would start appearing. Whether it's only in the new areas or the old ones as well is unknown, but Drilbur will appear in the Cool Hole. Yep, they finally managed to make those gen 5 overworld sprites. Good on them. What this means, in a nutshell, is that the usual mid-gen metagame revolution will not only come from move tutors (should there be any), but DW abilities as well. I don't know about you, but I find the prospect exciting!
