Ok, I will point out that the NEX 7 has a poor AF (just like I did in the A7R and X-E1 tests).
You made definite statements regardless of cameras used with statement like "However, it's realistic to state that the system performance will remain inferior to DSLRs in the foreseeable future."
This is a ridiculous statement when you even refuse to test the lens with faster AF cameras.

Folks, when did I start to propagate mirrorless cameras instead of DSLRs ? 3-4 years ago ? Something like that and this isn't really news for the readers in this forum. Ever since the Panasonic GH2 I am only using mirrorless cameras for my private sessions. I've never had issues with the AF performance from there on - I also mentioned this several times. A fast AF from a mirrorless cameras is also hardly a new concept. Most MFT and 1 Nikon users never had issues (except for 1st gen models ) - it's just fairly new for Sony. On the NEX-6 things improved but they weren't really impressive. Things changed at last with the A7 and A6000 albeit not with the A7R & A7s. So it's mostly better now - cool! No worries!
However, Mr. Wild came up with some aggressive statements and I'd like to hear a technical explanation from him why multiple 48-bit line sensors with dedicated amplifier circuitry (citing e.g. Canon regarding DSLR PD-AF) are inferior to much smaller, embedded photodiodes in a 42-bit sensor. The the CPU processing power of an EOS 1D X or D4s should also be quite bit higher than on an A6000.
This discussion is, of course, a joke, I know that.
Depending on the camera model, modern DSLRs have have a small advantage but the advantage is there and I don't think that this gap can be completely closed in the next few years. Just take the EOS 70D as an example. It has both on-chip as well as conventional PD AF. If the on-chip version was just as good then why would they have bothered with the conventional one at all ? Technically the AF photodiodes in a conventional PD-AF are just bigger thus more sensitive (better signal/noise quality).
Does it matter for most mortals - no. Does it matter for a few - maybe.
