Sony rep: a9 high ISO performance is similar to a7s, Canon lenses perform as good or even better on the a9

In a recent interview with Cameta Camera, a Sony representative made some pretty bold claims:

The high ISO performance of the new Sony a9 camera ($4,498) is similar to the Sony a7s ($2,598).
Canon lenses on the a9 (with an adapter) performed as good or even better than using Canon lenses on Canon cameras...

Here is the video:

A few other details from the interview:

Almost no reason for mechanical shutter
Strobes are currently designed for older technology like mechanical shutter
Any still camera overheats… but the a9 will be able to do better than previous cameras
It does 4k video almost better than any other camera out there… yet they left out slog and profiles
The sensor is so fast that flicker from LED isn’t really an issue so there is almost zero flicker/banding
Only lights that are very very slow should be a problem
High ISO to rival a7S (repeated from above)
Adapted Canon glass should perform as well or better on the a9 (repeated from above)
