they have "pre-order" links through the official site:

though it looks like none of the stores have anything but the standard edition listed.
I'll be stopping by my local GameStop later today and I'll see if they've got the TE in their system yet...
I'll probably get the TE through Gamestop just because I'll be able to look the box over for blemishes and say "give me a different one" if I don't like it, then get the KE through Amazon

The best thing about the arcade stick.... it has the CLASSIC button layout from MK3... as opposed to any of the weird layouts they tried with the newer 3D games... this gives me hope that the game will control like the old-school MKs.
