Even though no one really cares about this stuff except me.
Anyway, the Villager is in the same limbo weight class between middleweight and cruiserweight as Tanooki Mario. I did NOT see that coming, I totally had him pegged as a lightweight. Which Isabelle ended up being, so at least I got that right. It's a good thing the Villager wasn't one, though, because it was already the most overpopulated weight class to start with. We still don't know anything about Dry Bowser at the moment (no idea why we know EVERYTHING except for Dry Bowser), but super heavyweight is a safe bet.
As for the vehicles, the Streetle kart is an exact clone of the Blue Falcon, which is commonly believed to be the best vehicle in the game (if you're not me and you prefer outward drifters, that is). Yep, that makes MK8 pay-to-win, since you can't get that stat set outside of paid DLC. Meanwhile, the P-Wing kart is a clone of the Mach 8 and other similar vehicles - another popular choice. The City Tripper bike is a clone of the Pipe Frame and its reskins, and is clearly an outward drifter. Finally, the Bone Rattler ATV is a clone of the Tanooki Kart. The Leaf Tires are a clone of the Roller set (I'll probably end up using that, since it seems to fit with the Yoshi Bike nicely), and the Paper Glider is a heavy glider (as opposed to the Hylian Kite from the previous pack which was a light one).
This means this DLC pack has no unique stat sets (barring a surprise with Dry Bowser), though the Streetle and Bone Rattler, as well as the Villager, do if you disregard the first DLC pack.
