Update: Now that I've been playing this game for a few days, here's an update with a few discoveries on what has changed since Wild World:
* Kapp'n hums different tunes while you're riding the bus, and one of these is the melody that was used in the GameCube-version when he was singing while taking the player to the island
* The bird that can be seen on top of the Message Board only sits there tweeting whenever a new message has been posted
* The HRA office inside the city has Lyle as their chairman and will hold a theme-based contest every month, like who has the cutest room. The winner gets their room design displayed in a back room at the HRA office
* Phineas is the name of the walrus-looking animal in the town who is giving away free balloons and toys such as the bubble-maker for blowing bubbles
* The shoe-shiner, Kicks, can make your shoes match either your style or colour. This costs 500 bells
* Gathering points at Tom Nooks, like you did in Wild World, now has a new benefit besides giving you a discount after a while. Gather enough and you'll get a present for your patronage. There are 14 levels beginning at as low as 500 points gathered and ending at a whopping 10,000 points!
* The controls for the Wiimote's D-pad are:
Left and right - switch between usable objects, beginning with what you last used
Down - put away the item that you're currently holding (if there's enough space in your pockets to do so)
Up - look up at the sky (adjusts the camera so that you may look at constellations and whatnot of interest up there)
