They look like combined EF-RF adaptor with extender. The protruded part won't fit on the back end of RF 70-200.

Nice idea but no, they have an RF mount front and back.

My guess (repeat - guess!) is that optically, extenders work best a bit further away from the sensor - kind of the opposite of wide angle lens designs which benefit so much from the short back focus. Here the designers are fighting against it.

It'll be interesting to see what Sigma and Kenko come up with.
