Have a look at this https://bitcointalk.org/index.php?topic=1433925.msg20491019#msg20491019
So there has been an unofficial beta driver around for a few days. I also saw another user claiming he was testing it.

I'm still skeptical a little bit but my hashrate is exactly the same as before and effective hashrate is better than ever.
Unless this robinhood is some sort of evil genius with nothing better to do I would say the driver is legit.
