They've picked a lot of recent franchises, regardless of their success. Starhawk, Gravity Rush, Heavenly Sword, Fat Princess... Heck, the fact that Superbot was at one point considering a stage based on Lair speaks volumes.
I wouldn't actually be surprised if they picked a Folklore rep. It was a fantastic little game, the only downfall was that nobody owned a PS3 when it came out and it wasn't a strong enough title to move them on its own. But if Emmett Graves gets a spot, why not Ellen? Her game did better critically and commercially (and it also surpasses Heavenly Sword critically), plus Sony wholly owns the IP.
If I haven't mentioned Trivio in my post, it's because she is so beautiful and precarious that I just wanted to show her how much she means to me.
