A strong indication of NX using cartridges found.

Aren't SD/Flash cards not very expensive to produce compared to a blu ray disc. Ultra HD blu ray discs can contain 3 layers and store 100gb. Isn't that more logical for a home console. As for the handheld an SD card would do since 16gb is plenty for a handheld game, but consolegames need at least 32gb.
