The Legend of Korra: Book 4
It's a bit surprising that only two months ago Nick was streaming episodes of Book 3 on the internet. They have pretty much given up on the franchise and now seem to be burning through episodes. As is clear that tomorrow we get the first episode of Book 4 on the net and this isn't going to be aired on TV at all.
In any event, I'm excited, and here's a teaser for Book 4
Sadly, this post was probably more advertising than Nick has done for the season so far.
