This right here. When I play this level in Mario Kart I always think how cool it would be to just walk around a town like that.
I'll be very disappointed if nothing is done about my second request: preventing new houses from springing up over my carefully laid paths. I blocked and zoned as elegantly as I could in New Leaf but ran out of PWPs to enforce this level of control. This is a game-ending issue until the intruder moves out (and you can't do much to accelerate that either).

The power fluctuation in the reveal was a clue: the game will feature sim city style utility management.
In ACNL, one of the later updates made it so that villagers no longer move in on squares that have paths laid down on unless there is no other available space.
Online play in New Leaf (the most recent main title in the series) was downright awful. It would take around 2 minutes for you to go online, cause the game needs to connect to the internet, search, hide loading time behind animations, save your progress, then save again, and save one more time. It was a pain in the ass.
The real question is, will they show the penis on the statue now that the series is in high def?
An iteration on New Leaf with influences from Pocket Camp is my expectation, but I hope they keep the new Amiibos to just a few this time. They seemed completely overwhelming on the last go. That's my phoned-in expectation... I really do hope they surprise us with some things.
