one of the things they need to do it right, using DENA as a unified account system. Those VC games people who bought on Wii U (i doubt games bought in Wii VC), should be part of the digital move to NX platforms. why, this would help fans to be happy and they have those games and doesn't need to buy it again. Unless Nintendo is all about greed.
backward compatibility would be there is a form of digital games, Not sure on Wii U discs if Nintendo really wanted to use x86 architecture. emulation on discs would make it time consuming to develop i guess.
i'm still on the 2017 NX release date rather than 2016. we need to find out 2016 game lineup besides the few titles we knew. E3 is mentioned as transformation, is this a first phase of moving into what. are there any cryptic details behind this 'transformation' in a sense. gamers need games, and 3rd party jumped off the Wii U and that is a consensus, so NX should have 3rd party.
do it right and an early start, but Nintendo should have deals with 3rd party devs behind the scenes. If the NX games at launch is similar to the Wii U but couldn't add 3rd party devs current games, just ports of 6 month of games then it would really be just a Wii U situation all over again.
