It will most probably not happen but:
1. A Divinity strategy game that gives the full ooomph to the concepts set in Dragon Commander. Policymaking, a lot of characters, a massive Risk map. Real-time battles that utilize the geo-effects, and lite citybuilding.
2. DOS3, eventually. Taking the best from DOS 1+2, and the jump/throw/use random item as weapon aspect of BG3 (while BG3 is lovely, I personally like Larian's homebrewn RPG rules more than DnD)
