Reggie says Nintendo’s next console won’t launch until the Wii U is out of potential

[Soundwave]

Judging by how dull and forced Miyamoto's Project Guard and Project Giant Robot looked at E3 ... they are already out of ideas.

There won't be another traditional Nintendo console IMO, Wii U is the last one. Their "next console" will simply be a way to play their handheld games on your TV (hence one combined ecosystem). 

So the 3DS successor is in effect the successor to both the 3DS and Wii U.
