I really hope Link gets companions this time around. Save the world quests are much more fun with companions, don't you agree? Plus it would introduce more types of puzzles. By companions I don't mean a fairy but actual adventurers fighting for the same cause. Maybe there can be even be a companion that betrays Link later on. As Link grows older he should experience more adult things such as treachery, betrayal, and maybe even love.
By the looks of the trailer it looks as though Link still has the same battle moves from OOT. I want more moves darnsarnet! Moves such as sword parries, shield barges, kicks, leg sweeps, elbows, striking with the butt of the sword, hell even throwing the sword at an opponent. An older Link would have learnt a few more tricks that's fer sure.
