Jigglystep
Smash Ace
I've been a Jigglypuff main since Melee and stuck with her throughout Brawl, so hearing that our adorable pink puffball has been beefed up in Smash 4 has left me nothing short of overjoyed. Her overall damage output increased, back-air buffed, down-air now linking properly, up-air regaining its former speed, REST BUFFED, the list goes on.. Jiggs certainly looks to be extremely promising in this iteration, and I'm amazingly thrilled! 
That said, I decided to compile some key differences to her moveset that we know of so far:

Back Air seems to have increased damage (consistently doing 13% now) and heavily increased knockback! When Jiggs hits Kirby for the second time in the GIF, he was only at 53%! I repeat, 53%. With her great aerial mobility and offstage game in combination with this incredible knockback, just imagine all the offstage pressure you can apply and how easily she'll be able to net early kills.. Smash 4 seems to emphasize aerial edgeguarding quite a bit, and Jiggs is evidently no slouch at dishing out high-knockback attacks near the blast zone.

Up Air is much, much faster than Brawl. As of now, not much has been tested in regards to her combo ability, though it seems like this move would be great for linking from a down-throw or other moves with hitstun/less knockback, or perhaps even setting up for a Rest like it did in Melee!

Rest. REST. Just.. look at that hitbox in the first GIF. Need I say more? Aside from that, the killing potential of Rest appears to be somewhere in the middle of Brawl and Melee, as have quite a few elements from this game have been. Kirby is killed off the top with no problem at 64%, though this also needs more testing. One would imagine that he still would've been KO'd at a lower percent judging by how fast the knockback was.
All in all, I'm very hyped for her improvements from Brawl; I know she'll be one of my mains regardless.
Let me know if you guys discover anything from various gameplay footage of Jiggs.
