Why would they kill a cash cow?
Then again it is called Armageddon and has all the fighters from the series in it.  :-/
Why no Motaro?
From what some of the posts on the link have mentioned, it would be too difficult to include him due to the way he is drawn.
Hopefully, with so many characters they'll also be able to find a way to make them more balanced with regard to being able to pull off their special moves (i.e. Baraka).
I would definitely get it, though. It sounds very impressive. And the ability to create your own Kombatant clinches it.
