I doubt they left out content already prepared, the whole point of this is to make money, so they made the development skip some stuff to get it out the window so they could determine whether it was worth spending more resources on.
I'm sure they are making a bunch of new content for this expansion, but the hologram in game sucks - you can't jump, you have the equivalent of the lowest speed tier from the creature game, regardless of your species' attributes. I was really disappointed by it, especially with what it takes to unlock it. Anyway, I'm probably 50/50 on this, would be nice to revisit my critters.
