Things I liked :

Love the HUD, looks very nice...
Plants are hi res (and this is one the 360 ).
Dragon battles look like so much fun, cannot wait for that.
3rd person animations look great, I might actually use 3rd person now... although I think I just prefer 1st person. Infact, animations overall look fantastic
View distance is epic... as is the LOD. And this was from a crappy quality stream.
Camera bobbing while walking in 1st person.

Things I didn't like so much :

Responsiveness from sword swinging... obviously I'm not the one pressing the buttons, but there was a little bit of time before the sword animation starting and making contact with an enemy. Perhaps just speed the same animation up a little bit?
Didn't really see any blocking in that vid... would've been nice tbh.

Nothing else much to be honest
