Ultimate Marvel vs Capcom 3 General

I got a Mortal Kombat stick today. The button scheme is really meant for MK, it looks really awkward for any other fighting game. I would have been happy to give it a try, but I'm not sure if I really want a stick that I'll find out that I'm not really going to use much because I've never played MK (the stick does come with a redeemable copy of the original 3 games, I believe) and compared to how useful a regular stick will be for me for all the other games I really like playing.

So anyways, I've been leaning to the eightarc sticks in this thread for a while, but I recently heard about Hori's new BlazBlue Continuum Shift Extend stick. Is it worth waiting for the BlazBlue Continuum Shift Extend stick or should I go for an eightarc?
