seen this myself. xbox wouldnt accidently put that up if it isnt a solid date. sooo lets hope
If you can't wait for the xbox version I have managed to get Neverwinter on PC running flawlessly with an xbox one controller.
All you need are the windows drivers (Windows 7 or better) and copy of glovepie which is a free to download utility and a decent script. You are right, it is so much better with a pad. I've been getting top kill places in dungeon crawls and I reckon it's down to the use of the controller as I am rubbish at games:)
If you get everything working and want a copy of the script I'm using PM me.
