does anybody know if they have confirmed having trees in the game
They've said there's dynamic trees, yes. Trees with different weighted branches, etc.
I didn't know the Dragon-Shout was going to be R1, I guess I can start mentally preparing for that. I too liked the 'letting your enemies bleed to death' idea. Especially if that would work with an archer (ie, hit 'em in the chest, and they run around looking for you while slowly losing strength and becoming resigned to their fate- wouldn't it be cool if there was a 'heal others' option and they would perhaps beg for their life in exchange for the location of the dungeon's treasure and stuff). Regardless, new ways for people to die is always a plus!
