while I would hope this would happen, the animation angle doesn't really look like they would be kissing. Mostly because their faces are directed towards the audience and not each other, which would kinda be hard to kiss someone as well as it being very awkward to kiss in that position XD Besides, they already teased us with the "smooching buddies" in the season 2 promo, there's no doubt they'd do it again. XD The animation looks more like singing anywayON THE BRIGHT SIDE THOUGH, they are holding hands, not like where their arms are down but their arms are up like they're holding the others' hand pretty... passionately.
