With no physical BC, I still think it will have digital BC.
What I mean by this is:
1) Fully BC with all VC games.
2) BC with a slowly built-up catalog of 3DS/WiiU games. Maybe this will be like WiiU's VC was where if you demonstrate you owned the game, you can buy digitally on NS for some very low cost.
#2 cannot be full BC as the NS has no dual-screen functionality. So any games that utilized dual-screens are simply impossible to be on NS. But there are plenty of 1st/2nd party games that could be ported over.
