PixelBoy: This seems to be mostly new stuff, both new in age and new to bundles. If there are some things that have been previously bundled, they must be few individual items.
Star Trek/Planet of the Apes: The Primate Directive has been bundled before for sure.
Well, there are a few more bundle repeats but not nearly as many as I had feared - and some of those do even make sense. For example, the $1 tier remarkably includes the complete 60 issue (!) "Star Trek" (new) series - the first 49 issues were part of the earlier IDW Star Trek Bundles so they ARE repeats but of course for a new customer it would have been bad to only get $50-60 so there's no reason to complain (same with "New Visions" where Vol. 1-3 of 8 were in the earlier bundles).
The remaining repeats are "TNG: Hive", "TNG: Ghosts", "City on the Edge of Forever", Vol. 1 of the "Green Lantern" crossover and the "Planet of the Apes" crossover you mentioned. Notable as well: "Star Trek vs. Transformers" is missing the final issue (which hasn't been released yet).
But all in all it's a very good bundle (if you don't have a problem with the newer "Star Trek" series) that mostly builds on the earlier IDW Humble Bundles and even fills a few gaps concerning the older comics ("Alien Spotlight", "TNG: The Space Between", "TNG: Intelligence Gathering"). I'll buy it.
