couple observations from the new tomahawk vid as well as other random vids from E3, these will help clear up some of taxi questions.
BBB ending in FC is alright, the string isn't NCC so it will only be useful if you can get the interrupt on the last B into FC frame advantage.
Did see HOV B and also noted it has a lethal hit on it. I'm not really taking any stock in any movelist speculation based on the 2 videos we've seen. HOV A may still be in.
Old PO k (assuming you mean natsu PO k) is still in as PO 4k. She also has PO 6a which looks like natsu a+b and may beat 2a. Depending on the frames of certain transitions I think PO 2b might beat out 2a as well.
Regarding PO a ch, I've seen PO B connect for chunky damage. Just speculation here but PO B isn't super fast so I'd expect various other things to connect. PO 2b for forward RO, perhaps PO 6kk for oki. Even if it's just PO B I'd be happy with that. The pressure you can apply with PO looks insane now, the chip damage helps with that immensely.
Haven't seen any attempts at ws k ch combos. Though the FC 1ak string looks interesting as a low option from FC that could force people to try and push buttons.
I'm really interested in the new 6b string as well, pretty sure it's just 6bb as I saw a bunch of noobs just mashing it out on stream yesterday. The second hit that attaches the bomb is not NCC and is super linear. This move needs lots of testing.
New 3B does launch, not sure on combo potential. Perhaps a:6 still has a bound effect.
Speaking of a:6 the fact that it has a lethal hit is huge!!! We need to know the criteria and any followup damage on this asap. If it lethal hits just because you got the JF and even allowed something simple like 3kkk that would be insane. Best punishment in the game hands down, I don't even need to see the other characters.
BE doesn't exist, I'm pretty sure the PO 6b extension is available in soul charge.
The combo tomahawk showed off of PO 2a to ws BB looked cool and had decent damage. Interested to see if maybe replacing ws BB with caltrops would give toe hop stun to full combo. So much to test!!!
