Confusing premises cannot lead to sensible conclusions.

Isn't it amazing how close in performance the APSC in NEX is compared to the FF sensor on A99? If you look at the scores from DXO, it's not very different maybe half to at most one stop of difference in ISO performance.

First, you have to know what you're looking at, a comparison between different systems with another factor thrown into the mix, the SLT mirror, which makes about 0.5 EV difference as well.

But let's note your initial premise: half a stop is "amazingly close" or "not very different".

Even if you look at test photos, including the tests done here at dpreview the difference is minimal.

Did you normalize output in terms of output size (resolution on screen or print size), brightness, WB, saturation and contrast? All factors that influence visible noise.

I guess a bigger performance jump from APSC to canikon's FF but not to sony's own flagship FF.

So is the FF going to slowly phase out? Does the FF NEX even makes sense at this point? At maybe 3-4x the price, you're only getting marginally better results. Unless the FF NEX is expected to out perform the A99 significantly?

Again, you're throwing an extra factor into the mix that sets two systems apart (SLT vs NEX) and  use that blindly to conclude things about sensor size performance and future existence of FF in general.

If you want to put more weight to your argument, you have to compare like for lilke. You could start by comparing the RX1 (no SLT mirror, Sony implementation of the FF sensor) output to NEX 6 output (keeping earlier mentioned normalization into account), to conclude things about sensor performance relative to sensor size and future existence of FF.

Or compare the A99 to the A57 in a similar way.

Finally, before you might conclude that the SLT design is too compromising, I'd like to remind you of your initial premise regarding half a stop difference (amazingly close, not very different).
