I can only wonder how it'll end. Knowing Ueda-san, it's probably gonna be a downer and Trico *or maybe the kid* is gonna bite the big one. But I'm sure whatever happens, there'll still be that trademark glimmer of hope that every ending has.
the poll is leaning towards the baby griffin. Just look at him, they are making him too damn adorable so you feel close to it, and then... you know... just like in Ico and Shadow of Colossus
I don't know, in the actual game (well, trailers), he looks fairly 'wild', not exactly like 'omg kawaii! I wanna hugz it' cute, but yea, he does kinda come off as cuddly. Granted, I recall that Ueda-san wanted to make the creature as strange as possible so it comes off as fierce and not just some cutesy beast.
