Y2J isn't a heel yet, but they've been teasing a turn for ages.
Just watched last night's Raw myself, pretty impressed. Y2J being the Guest Ref for HBK-Batista at Backlash was a nice surprise, adds some interest for sure. Also intrigued by the prospect of another King of the Ring tournament, all in one night, next week. I'd imagine in terms of participants we'll see a few big names and some midcarders - they've got loads of main eventers on the graphic on WWE.com, but in the article it only mentions a few guys. It's tri-branded, so I would imagine we'll get something like:
HBK vs Shelton Benjamin
Big Show vs Umaga
CM Punk vs Batista
Mr. Kennedy vs Finlay
MVP vs Festus
Mark Henry vs Y2J
Batista and HBK cost each other their matches via interference, meaning Shelton and Punk advance. Kennedy beats Finlay, MVP cheats to beat the unpinned Festus, Y2J beats Henry in heel-ish fashion, and Big Show beats Umaga. Then we get:
Shelton Benjamin vs Y2J vs CM Punk
Mr. Kennedy vs MVP vs Big Show
Y2J wins the first one, again in heel-ish fashion, over Punk, and Kennedy wins the second Triple Threat Semi-Final after teaming up with MVP to take down Show, and then turning on him.
Y2J vs Kennedy in the final, an interesting tweener vs tweener match-up, which Kennedy eventually wins. Ta-da, Kennedy has the push they've been trying to give him for ages, gets put over by an established talent, and we have a ready-made Intercontinental Champion vs King of the Ring feud.
Seriously, I should book for WWE.
