It's just one of the new "Headhunter Packs" we'll be getting, "Pack" being the key word there. The general opinion from the videos are that it's going to be a smaller "Raid Boss focused" dlc, with more coming out in the future. No zombies were mentioned only a "Jacques O'Lantern" raid boss, and that it will have some throwbacks to the old Zombie dlc.
Also, to the poster who mentioned above, the Moon Base dlc doesn't look to be happening, it's actually looking like it's going to be a video in the likes of the Krieg Meat Bicycle. The Moon Base dlc was not announced at all. Here's what I and a lot of other people from the GBX forums took from the panel.
Level cap pack+ content: adds 11 more levels (will bring level up too 72) 5$ price point Coming soon (some time this fall) Involves Tanis and Lilith. Is a new map where Patricia Tannis will let players fight high-level enemies (which they can "over level" to create an "impossible" challenge) Does not require the previous level pack, you'll go to 61 rather than 72. FAQ on the requirements to come soon.
Also Coming Soon (some time this fall)

More character customization Packs coming soon.
