I'm expecting digital content to be fully Backwards Compatible (BC) and linked to our NNIDs (I expected it this gen with VC and WW). They can re-build a few digital titles to run on the new hardware like it is done on the PS4 or the digital BC performed by the XboxOne (PowerPC-to-x86). This promotes digital collections, and gives reasurance to buy more digital content.
Physical depends on what the NX is, I don't expect the WiiU discs to be compatible since I'd like the next generation to go return to carts (no noisy spinning optical drive). Now these cartridges could be like the 3DS if they want to maintain that BC, but if they want to try a new format then 3DS BC is out.
