I have no idea why Sakurai doesn't do this:
Side B: Egg Toss
Up B: Eggroll
When used on the ground, works like a normal eggroll.
When used in the air, The egg goes up in an arc followed by a rainbow, and at its peak, it falls into normal eggroll.
srsly, Sakurai.
That would be a pretty good idea actually, but then you might as well keep Egg Roll as side B and just have it aid recovery in such a way. Side B recovery moves are nothing new after all, especially now that Fox's Illusion doesn't even leave him helpless.
Speaking of, does anybody know if Yoshi still goes into helpless state after cancelling the Egg Roll in the air? Or is there ANY footage of an airial Egg Roll, at that? I really want to know how this works now. Bad as the move has been in the past games though, I still really like the move and I have seen it being buffed at least, since it turns around faster and I THINK it has more power now as well.
Also Egg Roll changes color with the colored Yoshi now, so yay for that ! I wonder why the other egg-based moves don't have that though, Egg Lay and Egg Toss still have green spots even if it is from other Yoshi colors.
Other moveset changes I guess could include him having that tongue tether recovery, and just a better grab game at that. Yoshi is always shown with such a long tongue in many of the non-SSB games he appears in, yet it's shorter than most other tether grabs in the Smash series. So, Sakurai! Give Yoshi his dignity back!
