Actually, it's more of the fact that for probably the past 4-6 months they've been primarily working on this Expansion Pack, while both the PC and Xbox Version of the original game is still extremely buggy (such as falling through maps, dinos phasing through floors), horribly optimized and now it feels like they're trying to push off the original game by saying; "look, SE is way better and we're going to be focusing all of our effort on it, instead of Survival."
