I just got that game and am just finishing things up in Flotsam, I am just wondering if a new game will be required for the EE (if so, I may just stop playing until it is released)?

i would suggest you stopping now and restarting it with the enchanced since there are new videos, tweaks and other things. Don't know if there's much changed before the point you are but i guess it's better to just restart it

I've been waiting to replay because they are adding so much I would rather get the whole new experience at once instead of having to restart partway through a chapter.
