I dunno, two years (or 1.5, depending on how you look at it) isn't unreasonable for a major expansion. I'd hate for that to be the reason that people give up on the expedition. However it is a long journey, and I totally understand if people don't want to cross the far side. It's a lot more distance than just heading into the core, since the bubble isn't out on the southern edge. Getting into the core is enough of time commitment that I totally understand when people don't want to go further.
