-The NX won't be as powerful as the next Xbox or PlayStation 5. It will be around the specs of the PS4 (not the PS4 Neo) and will not support 4K.
-The NX won't have included storage above 500 GB (it's pretty unlikely that it will even have anywhere near that).
-The NX won't have most multiplatform releases and will have few third-party exclusives.
-The NX won't support Wii discs ( I think that's a given).
-The NX won't have a wide variety of Virtual Console relases at launch.
