Carts, well, they can project a console without a big device in it like a disk reader and desing better consoles in terms of heating control.
Also, a big problem nowadays is that you have to save the disk content on the HDD, because it is faster than read from HDD than on the disk. If cartridges get rid of having to saving content on HDD, it would be lot better.
Only advantage of disks is the cost(well, also compatiility with old systems). But a 2010 technology 8gb disk have been sold at 20$ to 40$(the 3ds ones) with profits. with 2017 technology, i think that a 32 to 64 Gb could be affordable for 60$ selling price.
