Aren't some (the cheaper) microSD cards really slow? Is there a minimum speed class supported? https://en.wikipedia.org/wiki/Secure_Digital#Speeds
If not, people out there might be buying the 12.5mb/sec cards for their console, for price reasons. Game load times will be enormous, and can affect even the viability of open world games and multiplayer games.
Digital is no-go. I don't think third-parties will like the lack of patching support and DLC. It could be in third-parties interest to kill support for this console early on, so they can go back to their space-consuming ways. The modern AAA consumes hundreds of gb by the end of its life (latest CoD has a required space of 120gb).
