Life after Wii?

Yesterday we reported that GameCube games could come to Wii U via WiiWare, and Nintendo has now released an official (and very carefully worded) statement to Destructoid:

To clarify the capabilities of the Wii U system: As correctly stated, Wii U will not play Nintendo GameCube discs, however Nintendo has not made any announcements regarding downloadable content.

Both statements of fact, of course: Wii U doesn't use GameCube discs and Nintendo has said nothing about WiiUWare or Virtual Console for Wii U, but could the two dovetail together?
