Quoted from metallik:

Nothing to do with remakes here... mine's for sale because I've had it for 4 years and it's time for something new. My roomie at the time really liked the game but he moved out a few years ago, and MB was never one of my favorites. I have MB, AFM and MM, and MB is the least fun to me of the three. Would rather have Metallica or Creature or some tough early SS games.
That said, I really don't think there will be remakes past Medieval Madness. After the initial surge, demand seems to have fallen off dramatically. There's a MMR available right now at $500 under cost, and the games are supposed to go into production in a week. Does not bode well for other titles to be remade when the king-daddy of WMS games is selling under MSRP before it's even built.
Get yer MBs now while the remake rumors keep prices low
