Hmm
Console Storage is going to become a bigger and bigger issue, as everything's slowly moving to Digital by Default. Credit where's it's due: The 360, PS3 and PS4 have internal and user-upgradable hard drives - Wii U and XBone support plugging external drives in, but that was always a slower, more cumbersome system (Really don't get why MS Removed that feature)
The big question is what will happen with Nintendo Switch: Anything bigger than a micro USB Drive will be impractical to take on the road with you for your digital content, but how much storage to they dare put in the systems without making the launch price unaffordable?
best case scenario: it has a MicroSD Storage slot, like the 3DS Line. Bonus points for including a 32GB+ Card with it.
