For me, personally, I see this happening over a series of decades... just like silent films and 1950s television. Even if chip music itself survives over the years, I don't know how well today's games will (or even the games from 30 years ago... yes, I almost think they might actually outlast today's games interestingly enough).
I think the SNES has had much more staying power than some of the other chips I've seen over the years for the sheer variety of sounds you can get off of it. You can even do pitch modulation with almost any sample that can fit in there. The only catch is that you have to actually program a sound driver for it or use something that most likely converts tracker modules to SNES music (I currently use a hacked version of mukunda's SNESMod when I want to get really fancy with pitch modulation and noise, and I'm thinking about making my own so I can swap data in and out). My fandom for the SNES is older than this very username, personally.
For the NES, I have an idea in my head on how to pull off some psuedo-DPCM synth, whether it be by changing the reset point or rigging the starting value each time. Other than that, I'm not as interested... and this is something that I have known since 2007, finally went authentic in 2012 thanks to Battle of the Bits (and it2nsf), and then... I'm currently not as interested. I just don't quite see the variety (and when it came to Famicompo Pico, I ultimately failed to vote because nothing stuck out to me... not even something extraordinarily bad).
