Quickly skimming through the dpreview preview, I note the phase part of the hybrid AF is only effective in the centre region with a coverage area smaller than the 9 point diamond. Of course still an improvement over what was there previously, but it is no mirror killer (yet).
Also they say the STM lenses are focus-by-wire. Let's just say I'm not a fan of that...

They "have" to be focus by wire, as the lens has no traditional gearing system due to the stepper motor.
