I am expecting 2 endings, or one ending with an extra cutscene. I feel like something extra is going to go down if you saved or freed both blue birds and left their nest alone. There is some symbolism going on there.
Oh and I rewatched the winner announcement scene and Victoria hands the mic to Mr. Jefferson when she ends speaking and we can hear him talking all the way until Max and Chloe leave, so they leave first.....I think he may indeed have similar powers to Max (or know a shortcut to the junkyard, which I very much doubt, as Chloe goes there a lot)
