Yep i was referring to how long she floats. Though it's unfortunate to hear that extra bit of information....
I counted, it's 4 seconds, I think that it is the same as melee.
Peach has been buffed in many places, but has been nerfed in places she was good at in melee, but I think she is still comptetive.
Edit: Actually, I have A LOT to tell about peach.
Her double slap is one of her best approaching moves, seems so, it has a lot of range.
Her Dsmash isn't that bad, it's actually very useful and sometimes do a lot of damage.
Her new up tilt has a lot of range though I didn't have the chance to use it a lot.
Her down tilt has lots of range and is very useful.
Her side tilt seems useful too, but I'm not sure.
Up smash is almost the same, dashing is VERY VERY useful and good.
Side smash is very very strong, it gave me lots of kills.
Now floating... her areials are useful, but NAIR doesn't come out fast anymore like in melee, but it is still very very very useful, her DAIR is one of her best moves now, it kinda stucks the enemy in, it has nice range, and believe it or not, it makes the enemy fly UP after some hits.
FAIR seems like it gets a bit further than melee, but the timing is more or less the same, actually, for me it seems even more useful than melee's.
UAIR seems like it has more range than melee, but I didn't use it much
Now specials... well, veggies have been nerfed, they seem to be less useful, though if you look at my vids, I killed with a stitch face, that was the only time I actually killed with a veggie, never happened before or after - the veggies are easily caught too, so it can work against you.
Side B seems like it goes really further, but it doesn't have much priority, it isn't THAT useful, but maybe only against Sheik, who knows.
Up B is the saddest part of peach... it is EASILY punished, once you had to use it, it is really easy to hit you, you can't use mind games anymore cause closing the umberalla is just like opening it... though I killed with the umberalla once XD
her B seems to have more knockback this time, but still - don't use it too often, it has lag after using it, so only if you are sure you are getting hit
And that's about it... from the many hours of one day I've been testing her, that's what I've found.
