I can't say that I am a huge ACDC or Metallica fan but I own both machines now purely because they are good games. As long as Gomez doesn't design it I can see Kiss being a big big seller for Stern. They are due for another big title after Star Trek and Mustang which have been relative flops compared to ACDC and Metallica. If Stern follows the recipes of those machines it will be a success.
Both Metallica and ACDC were huge hits for Stern. I agree for it to be a winner it will need to have killer gameplay or it will just appeal to the die hard KISS fans only.
Not sure if S.R will be on it. I can see the L.E version going over $12k from the factory if it happens. STERN are due a big release soon as Mustang was a flop....Although the teasers on Facebook suggest another game before KISSRR (or what ever it will be known as)
