Speculation: Will Smash Bros NX and Mario Maker NX online need to interact with Wii U?

[nuckles87]

The heart of Mario Maker is its user created content, so it'd be a huge waste of Wii U levels weren't playable on NX, and vice versa.

With Smash Bros, I think it would be preferable if NX people could play with WIi U people and download their levels, but also far less critical to the experience.
