So would anyone like to make any guesses of how many total units both dual-systems ecosystems will sell.

Is 3DS + Wii U an ecosystem?

How?

Because they share first-party franchises, the Mii-Verse, and eShop credit. Not to mention we've already seen games that work in conjunction with their couterparts on the other. Smash Bros and the eventual Pokemon Stadium style game being good examples of whats to come with Monster-Hunter and Sonic Lost World already have tapped into that.

Did you really not know?

I own 3DS + Wii U and PS4/PS3+PSVITA. But how to use Mario 3D World and Mario 3D Land together? I don't know.
PS4/PS3 and PSVita share online account. PSone titles work on both PS3/PSVita. That is clear for me. Some games on Playstation are cross platform (like Guacamelee, Superfrog HD) with cloud saves.

So - I should use one nintendo ID?

Does Virtual Consol titles work on both 3DS and Wii U like PSone titles on PS3/Vita?

Are there some sort of "cross buy"/"cross playable games" on Nintendo systems?
