I want to say ive seen this confirmed via forum posts. Anyhow, heres the question pasted from the FOV faq:

Can I continue playing with my character from Divinity II - Ego Draconis?

Yes. You can load any savegame you have from Divinity II - Ego Draconis and continue playing. When you reach the end of Divinity II - Ego Draconis, the story will automatically continue and your character will keep all of its stats, items and skills.



I think I might just start a new character in Ego Draconis and play through to tour the modifications to the first game. Im really curious in just how extensive the new version is.
