I'm actually most curious as to how her puffballs/star things work right now, specifically as to why I don't see japanese players using them more. For the few times I've seen them get used, they seem like they
should be a really good move. Main place I'm looking is
http://www.youtube.com/watch?v=caks9HBD2QkNotable points are at 19:56 and 23:02. As we can see here, only two puffballs came out, and the player instantly jumped afterward. Also, 23:11 and 24:24, where a single puffball was used with what also appears to be a JC. Additionally considering that in Leo's vids, when he tried to use the 3 puffballs and run after them, he took much longer to move, I think it's a pretty safe bet that there's a JC window on this move.
A move like this... honestly, it feels like something from the touhou fighters. Coupled with all her other great projectiles, as well as
flight, I really do get a touhou-esque vibe from this character. Anyway, it looks like it has relatively low startup for a projectile you can approach with, and it also seems like a good option for harassing your opponent from fullscreen, giving you coverfire while you go to the air.
I'd wager even the non-EX version could be good for meaty on wakeup. Depending on a couple of factors, such as how long it takes for the puffballs to become active and/or if you can fly-unfly to quickly execute a low to the ground aerial, you could use it as an enabler for some pretty beastly mixups, without much fear of retaliation.
Using puffballs mid-blockstring may or may not be an option. At 22:00 in the vid I linked, the player tries to use it from point-blank for pressure, which just got them hit, but if you give yourself enough space (such as from a max range 2c, as was done at 19:56), it might be safe against some chars, and lead directly into more pressure.
Finally, the EX version looks like it could be abused greatly from a midscreen knockdown. EX stars -> fly above their head for repeated ambiguous crossups.

Actually... after all that, I think the "most interested" bit was wrong. Make that "second most interested." What I'm
most interested in finding out are the specifics of her fly. Can it be canceled into from moves that can be special canceled? Moves that can be jump canceled? Can it be canceled into at all? Then there's the matter of what the minimum time you have to spend in flight is, and if it has cooldown when you cancel out of it. Lotta unknowns.
Man, I've been looking forward to a new PC release of MB for a long time, but this character makes the wait for MBAACC even harder. =p
