Neverwinter Nights 2: DM Client Download on Day of Release

According to Shane DeFreest and community update #10:

So, this week we're going to try and load you up with information to help clear the air and set the record straight on a few things. The first being the DM Client. The DM client will not ship with the game in the box. We looked at a number of different scenarios and the best one that the team decided upon is to release the DM Client in full as a download the same day of the release. So while it will not ship in the box it will come out with the game. That's the official word as of today.
