The last reason not to buy a camera is the lack of popup flash. They actually do you a favour, because all on camera light does is wrecking the shots. If the light sucks, use a proper flash (bounce or use off camera) or change the composition. /rant
Swivel screen would be nice, I agree with you.
EVF - well that is a no go still. The only thing I would take now would be old hasselblad style 5" screen if it was fast enough. I don't think they are YET. But it is getting there, lets wait for responsive 4K EVF.
Pretty - that's a personal opinion issue. I personally don't care because it's a tool. Just like a carpenter doesn't complain that a hammer X doesn't look as good as Y. Same thing here. If you want pure fashion just buy a Leica or paint a red dot
The real odd one is no phase detect on A7r. Why on earth would they do that?

Anyway - the real message here is the new system, new direction. You could guess A-mount is replaced with this. That is the biggest news here.
This will be the first and perhaps flawed attempt. Look at first NEX and at first MS Surface. But they got a lot better. Even the lenses don't appeal to me yet. f/1.4 primes and 24-70/2.8 would be the first ones to release, and they put in 3.5-5.6 fail
