I was happy enough we didn't have to wait 3 years between the main films, but now year n a half, well :)
Assuming they already have a general outline for VIII, it sure would help themselves a lot and be a great time-saver if they can manage to store away and port over any necessary props/set/models from TFA. Sure beats having to rebuild them from scratch again (such as the Millennium Falcon, if we see it again).
