Even if it doesn't bring in a bunch of new players by itself, as @jarvie said in his comment it will add a lot of credibility and prestige to the project. Additionally, we will have the rights to the video segment after it airs, so we will have a professional quality commercial for the game that we can use going forward, which will be a huge improvement from the Kickstarter videos we have now.
We will let everyone know the time slot once it's set but as of right now it should be sometime during the last week of January.
