My personal feeling is no.
The motion element of it just doesn't work well for realistic reasons .... you can't have feedback to a device like this (ie: in real life when you swing a sword and hit another sword ... you have feedback). The Wii can't do this.
The Wiimote can't even sense depth, meaning it really just measures which angle you're swinging the remote around, it can't pick up things like you thrusting the controller towards the screen.
Ultimately all this leads to basically games with stripped down/casual mechanics that are shallow experiences.
And really Splatoon shows you can implement the aiming nature of the Wiimote into a regular-ish controller just fine too.
The future of this tech will be VR applications, but Nintendo doesn't seem to have much interest in VR.
Gaming doesn't need the Wiimote for casuals anymore either ... touch based games with no buttons whatsoever are even simpler and easier to play than Wiimote games and smartphone gaming is quite frankly bigger than the Wii or even DS ever were with casuals. So that need in the gaming ecosystem is gone too. Casuals have thousands of easily accessible games in a control factor that even 3 or 4 year old child can use easily (reaching out to touch something is basically the first thing we learn to do as babies).
