It's good to see such a classic will come to life once again. For the digital distribution I hope you are planning to release it on gog.com. I usually buy my games (mostly RPGs) from this site, because of the non-DRM method they're using.
Also, I hope you will add an editor to create our own adventures and levels.
I already have the boxed version of Divinity 1, but I definitely will buy it again if you will release it on gog.
