I do think Divine Divinity is on par with games such as Diablo II or Morrowind (successful games from more or less the same time of the decade). Blizzard and Bethesda Softworks didn't get the incredible sales on their admittedly fine products by being quiet. You have to create some "buzz" about the new game or I fear it will be another great game that very few people have heard of or buy (and if it's anywhere nearly as good as Divine Divinity it deserves better).
I know everyone has their noses to the grind stone with the game (and that's great). But when the faithful here in the forums started to have doubts it was even being worked on anymore there's not enough information being leaked about it.
