One can easily select worst case comparisons and say there is no point in the Sony system, but its not the whole story.
Even with bodies alone, you save 1Kg on two A7/R bodies in a kit bag over 2 x DSLR. Throw in a 100g 35mm FE vs. te Canon or Nikon alternatives (f2 lenses) and you save yet more weight (as well as getting far superior optical performance at wider apertures (compared to F2 models)). Sure, the 55mm f1.8 FE is no lighter than the competition, but optical performance is astonishing. Again, to compete here you need something like an Otus at megabucks and megaweight.
Then there is bulk. Try fitting two A7 bodies, a 35mm FE and a 55mm in a small bag and see how much DSLR kit you can fit in the same space....
No, the Sony mirrorless system is not a panacea, but to suggest people are switching systems for no reason other than to stimulate bored minds is to ignore the facts.
Yes, it would be great if Sony produced a line of fast lenses where users only benefit with lighter bodies, alongside slower, compact offerings for those who dont need wide apertures and want to benefit from the smallest package. Maybe that will happen in time, as it has with Leica, but the greatest noise (ironically) was from those who were irked by the slowness of the early releases! Personally, I want the small, slow optics, but the masses spoke.
The anti-A7/R arguments also assume that Sony A7/R cameras are considered only as 'only' systems, or to the exclusion of others. I shoot Canon and am happy with that. I do not want to switch to Nikon just to get more DR and resolution. A limited buy into the A7 system has given me my solution, using the excellent metabones.
Regardless of some not so small lens releases, the Sony A7 system is still very useful to a lot of people and it is here to stay. The splash is only going to get bigger, I am confident of that. Just because it does not give you exactly what you want does not mean it is 'pointless'. I do agree, however, that they need to get moving and produce a killer high quality compact (slow if need be) 24/25mm prime (not sure the 28mm/21/16 convertible thingy will be optically good enough, but we will see) as well as consider some very compact (slow) longer lenses for landscapers.
