I'm not sure if you're more hyped than me man.
I, for one, couldn't care less about any "downgrades". Graphics are the last thing I look for in any game. Don't get me wrong, I can appreciate a good looking game, but it really is at the bottom of the list of what I want in a game. This game especially is all about Geralt and the story for me with the exploration and other RPG elements coming in at a close second. It could have run on the same engine as the first Witcher and I would have been just as hyped to play it.
