I did some tesing and have come up with the following info:
The cross-over tatsu can only be done when the opponent lands with their feet towards you.
It can be done after techable knock downs as well as untechable ones.
You do land at what i believe to be +4 frame advantage (possibly more), but unless you perform the tatsu “into” a corner, the pushback is too great, even to land a kara-fierce DP.
It DOES NOT hit crouching opponents, nor does it stand a crouching opponent up (major bummer).
You can perform the cross-over tatsu anywhere on the screen and it works after the following situations:
Sweep, lk.tatsu.
lp.DP, dash forward, lk.tatsu (on grounded opponents).
Forward Throw, lk.tatsu (crosses over), lk.tatsu (cross back over and hit).
After a fake U1, lk. tatsu (crosses over), lk. tatsu (cross back over and hit).
Because it whiffs on crouchers, I can’t really see it being useful, but it does look cool if you do a fake U1, cross over twice, end up in the corner and combo off the cross-up lk.tatsu!!
Because I was playing around so much with Ken’s lk.tatsu, I forgot to see if it worked with any of his other tatsu’s. I’d assume it would work, but there would be no follow-up attack obviously.
Just on a side note from this, does anyone ever use a lk.tatsu immediately after a FADC’ed fierce DP to cross-over? I haven’t had a chance to put it into a match yet, but I thought that it has potential as another mix-up to add to Ken’s game instead of the guarunteed damage from a mp.DP.
Due to the fact that the FADC’ed DP is a techable knock down, it doesn’t really work like a proper reset opportunity (unless it’s a CH) because the opponent can see Ken dash under well in advance, but the lk.tatsu “obscures” the opponents wake-up animation, crosses them over AND leaves you at + frames for the meaty cr.lk or whatever wake-up games you fancy…
I don’t think there is time to step back and make it an ambiguous cross-up (like you can after sweeps, forward throws and Fake U1’s), but you can switch in a lp.DP instead of the lk.tatsu to stay in front of the opponent and still land at + frame advantage. Slightly lame compared to say, the mix-up madness of Abel and Ibuki etc, but a mix-ups a mix-up right?
Peace,

P.S. - Slowly getting the hang of the stick. It’s been a week now and I can almost do everything I could before. Still struggling with the Ultra motion after a FADC. I’m getting a lot of ex fireballs and ex DP’s that I NEVER got before on the pad. I can do motions much quicker than on the pad, I just lose where my fingers are in the heat of battle and end up looking VERY stupid indeed…
