One of the main attractions I see is that we now have lenses that can actually make real use of a 36MP sensor. Sony's Zeiss-designed FE lenses are rated for extremely high resolution, and you have current and incoming Sigma lenses that can also take advantage of it.
Even better are the adapters that allow communication and AF with Canon lenses. What's not to like about having the sharpest zooms, telephoto primes, and tilt-shift lenses on the market usable with the best sensor available?
There are a lot of things here that I sort of disagree with. However, my disagreements are matters of philosophy and not necessarily simply because any one answer is inherently right or wrong.
If your goal is simply to have the highest MP sensor on the smallest body possible then I suppose the A7r makes more sense. However the A7 has a hybrid AF system with significantly more AF points than the A7r. The A7 has a quieter shutter (which if you're trying to take a small camera into the street is useful). The A7 has a higher burst rate (both camera's are pitifully slow, but still, the A7 wins slightly in this regard). You'd probably never use it in a studio (some might) but the A7 has a faster flash sync speed.
I prefer the camera that I can use in more usage cases. If the point of the system is to take it everywhere and do anything, I think the A7 has more useful significant advantages. It's not just how many MP the sensor has to me, it's the entire package. The A7 offers the package. I feel this way about full sized cameras as well. If I had to start over with a clean slate and no gear and had to pick a dSLR, I'd still buy a Canon 5D3 over a D800 or D800e for many of the same reasons I've already mentioned here (I also happen to prefer Canon ergonomics and glass, but that is a side point).
I also personally don't see any real point in having more MP than 20. Whether you're in Print or Web even 12MP is more than sufficient. 36MP just means massive files that for the most part and for most applications I'm going to shrink down anyway defeating the purpose of having them in the first place (most of what I put up on the web has it's longest dimension at 2048px across). We could get into the discussion of making extreme crops as a usage case, and it saving you that <1% of the time in which you've made that error, but I am still a part of the crowd that feels you should get it right, in camera, the first time.
I should also mention that as 'great' as the 36MP sensor is, it still pales in comparison to a lot of other systems. We haven't talked about anything in medium format. If the goal is just to talk about MP, sensor size, and glass we should be talking about the new Phase One CMOS sensor or any of their 'older' 80MP backs. Even still the point of Medium Format isn't the MP, it's for the sensor size and dynamic range. I say this to say that I don't believe that having 36MP makes the A7r or even the D800/e have the 'best sensor available', and I don't really feel that only a single part of the camera should outweigh every other part. To be clear, does the A7r take excellent images?: undoubtedly. Is it a camera that I would personally want to use?: No, I think there are other better options on the market that fit my usage cases better.
In short, I don't think the A7 with it's 24MP is lacking in any real way in comparison with the A7r. I think it's a more usable camera in more usage cases and it costs less. But like I said in my previous post, I wouldn't buy either with my money. I'd much rather have the upcoming Fuji X-T1 or an 'older' X-Pro1 which effectively has half the amount of pixels as the A7r.
