OK, guys. Please stop with the speculation. Here is the official word from an email from Steve himself when I asked if it would be KISS:
"The band tie-ins have served Stern really well in terms of sales and player feedback, but they can be difficult in terms of crafting interesting shots and modes that fit with the theme and the individual songs.
That's why Lyman and I are working on a TV license this time around, which will give us more of an opportunity to craft a game with a cohesive story and more unified shots and modes.
I can't give you a lot of details, but I can tell you that our next game will be "Cagney and Lacey," based upon the hit 1980's detective show. We are still working out a few of the details with both Tyne Daly and Sharon Gless, but they are both slated to record new voices for the game (I'll be doing some as well). Players will get to experience the excitement of this interesting take on the cop/buddy drama, and I think it's going to be the best game we've made yet!
More to come --SSR"
That's the official word.
