That Cactus Canyon/Medieval Madness project has been in limbo for years donnyman. Years.
At this point, sending them money to "pre-order" is the equivalent of burning your hard earned dollars. Sorry, but thats the truth. There is a better chance of the repro house (the guys that built a special run of "Big Bang Bar") to build out new reproductions of Capcom's "Kingpin" with this much time gone by.
Bally/Williams only exists in the form of games out there in people's collections or on route. If you want an NIB machine, and want to keep pinball sales going, order one from Stern (Iron Man. Big Buck Hunter Pro, Batman Dark Knight, or Shrek).
