Stern will only work on legends of rock for their rocked themes games. Forget your favourite also-ran bands that take up so much posting space in this thread. These pinball machines have to sell, and sell well, and sell well inside and outside the USA.
Stern is a business. It needs to make money to survive. It does not exist to make a machine for your favourite garage band.
That's why, eventually, we will have a QUEEN pinnie. Apart from the Beatles, there is no super-mega-world-wide-legend-band that will sell more machines that a QUEEN themed machine.
Sorry my USA friends. It's true. ACDC, an Australian band has set the pace for pinball sales. Queen, a UK band, with massive USA exposure, will come close to that hit. No other rock band will. Not Metaliica. Not Areo Who? Not your favourite "never heard of them outside the USA" band.
