I'm hoping for two things ;
John Trudeau to design the KISS machine
The Originals depicted in the artwork - small references to past members acceptable
If the artwork depicts the cover band line up - It will flop - no matter who builds it or designs it. The current US tour is over. They will be concentrating on the Euro Festivals and the tour downunder.
Trudeau just completed Wrestlemania - so I really doubt he has done KISS and therefore it can't be next. Game of Thrones is about to air the new season, and the first episode will be the most downloaded TV show in history. So perfect timing for the new Stern. Would be a marketing coup to get the game ready now.
The more they delay the KISS game, the better it will sell. I'm told that the band have 1 or 2 world tours and then they are done.
In fact, do the KISS game LAST - because if they do finally close the curtain for the last time, it would be a "one off show" with the original line up.. That would be massive.
