A Vegas style town would be amazing! Although, it wouldn't really make sense without cars... well, it would. I just really want cars!! Just watch, they'll end up putting an entire gondela/waterway system in rather than cars because 'it fits the theme better'!!
Not gonna lie, but if we get bunkbeds before cars I'll be slightly annoyed. Cars were 'promised' before the game came out and bunkbeds seem like a fairly recent want (correct me if I'm wrong).
Bunkbeds do make sense as the devs seem to be releasing packs with a coherent theme lately (TL, EL, NK) and bunkbeds would fit with these latest packs. Plus they're probably easier to animate than cars...
