While it's a given that cartridges are studier than discs, I can't think of any games I've personally messed up, save a few SEGA CD games that we practically used as coasters because I didn't care about them back in the day (and still don't).
I can't see any console manufacturers going back to carts for the sake of sturdier media anymore than going back to analog tape and 8 tracks encased in hard plastic shells instead of audio CDs.
The only future for cartridges is in early childhood consoles like Leapster, and even that's going to be phased out in time.
