I think Nintendo may make a Mini-console which can play smaller sized cartridge games which are the size of a SD Memory card sort of like how Sony made the PlayStation TV/Vita TV which can play Vita game cartridge games on TV, and use the PS3 controller to control games.
There maybe a lot of people who may buy a mini-version of the Nintendo 64 where they can buy physical smaller sized cartridges for playing games like Super Mario 64, Golden Eye, Turok, etc.
It maybe less likely for Microsoft to make a mini-console where users can insert physical games into the console. But, if mini-consoles from Nintendo and Sony becomes very popular,
or Microsoft wants to sell consoles to poorer countries, there maybe a possibility that MS makes a mini-console version of the first Xbox where gamers can buy Halo 1, Forza, Fable, and other games.
