Well Chanyeol and Pyo (http://www.youtube.com/watch?v=b6xs0R42G_U) know each other too and that's a pairing I would read. I'm getting hot just thinking about their voices :D Also, didn't Yukwon say he dances better than Kai? There's something to explore XD
I'm keeping my fingers crossed that there's more because I like both of the groups a lot.
