It's pretty annoying to buy Wii controllers these days. You need a Wiimote, sure. But then you also need a Motion Plus add-on to make it more accurate. And don't forget a nunchuck! In the end, you need three different components for a single person to fully experience the Wii, which is a little absurd. Luckily, Nintendo is prepping a "Wii Remote Plus" which combines a Wiimote with a Motion Plus.
It's a pretty natural thing to do, since the Motion Plus essentially fixes the crappiness of the original Wiimote. It's actually surprising that it's taken this long for them to release a unified remote.
And it's not even officially announced yet! This just comes from a leaked ad for a game called FlingSmash, which promises a free Wii Remote Plus inside. But it should be coming soon, in any case.
