Not in their conventional(SNES, N64, Genesis, NES) form, zero chance. Too expensive, too limited in storage, too many restrictions on production. The audio on todays games wouldn't even fit on the biggest Nintendo 64 cartridge(Resident Evil II from memory, at 64MB).
I do miss the feeling of loading up a cartridge though. The Nintendo 64 was just a well built console in general. I have a brand new Jaguar that I haven't un-boxed yet so I can relive the cartridge experience once again :P
