One possible future I see for the series: migration away from the consoles. Just buy Rock Hero, plug it into your TV, plug in the instruments, and play. You aren't limited to four instruments (except perhaps by screen size, but that's becoming less and less of an issue). A song could use as many of each instrument as it needs, and probably some other instruments (like keyboard) that aren't currently provided. There's no expectation that a given song will use all the available instruments. Perhaps the publisher strikes a deal with the RIAA, and all newly released tracks get a version for RH that you can buy and download.
