Gain of Fair/Foul Winds is going to help her a lot too. And if she does better damage she is a VERY competitive character in UMVC3. Justin also said her normals are better (which is my only personal complaint with her) and he definitely seems like he's gearing towards playing her in UMVC3.
I came up with a Vergil theory fighter SS combo in my dreams last night. 3 meters just for style purposes.
st.L, M, H, Summoned Sword (wait a bit let the swords hit and then dash up just as they are about to finish),M, H, Lunar Phase, QCF+S (formation set to Storm Swords), H, S (start charging up L) air M, H, d+H, d/f+H, Storm Swords start hitting keeping the combo alive in mid air, release Round Trip while in mid-air, j.S, d/f+H, Maximum Judgment Cut hyper for the finisher.
The Storm Swords cause a ton of hit stun and if you time your combo just right you should be able to solo continue a combo after d/f+H OTG and then do more damage by releasing Round Trip as well. Storm Sword gives you a day to do anything you want and that's where you will be using Round Trip charge.
Depending on how long it takes for the Storm Swords to come down, I may need to add a Stinger wall bounce to the combo as well to prolong the duration. Combo probably does shit damage for 3 bars but if someone pulls off something like that the crowd will get crazy hyped up.
