If you mean the post 'Status update July 23rd' I think Lar was referring to Project D unless I missed something somewere as I don't visit every day. As far as I know Project E will be the spiritual successor to Divine Divinity which I suppose you could call Divinity 3. As speculated by a few it will probably involve the Divine and Damien but like you say only Larian can confirm anything. As to what the game entails we can only guess until they announce anything.
