If Nikon makes a 50mm 1.2 with AF, a 135mm f/1.8 and radio flash units, I'd jump ship at that point.

i have 2 Einsteins and i find them to be very reliable and built much more solidly than the older AB units. i have not yet tested the high speed flash duration of the units but it was a feature that i liked having if the need ever arises.
some other nice things about the Einsteins:
1/10 stop variation in power over a 9 stop range
ability to control power of multiple strobes via camera with the Cyber Commander unit
value vs quality (its just a good product for the cost compared to other brands)
i have also not had any issues using any type of modifier with them. i got the units when they were first released and i was aware that they were going to correct how modifiers were attached to the unit. as i understood it, occasionally a large/heavy modifier could "jump" off the unit so PCB planned to extend the length of the clasps that engaged the speedring that the modifier was attached to.
i have never had an issue with this and i have used up to a 36x48 softbox on these units. i do hope to get a 54x72 softbox in the future so at that point i might send the units back in to get them updated to handle the extra load.
bottom line is that i find the Einsteins to be well made, reliable, and very very versatile. but i would try to research how they perform at faster flash durations and if they are capable of what you need. the only other units i saw (online) photographers using to do such work were ProFotos...and they are beastly expensive.
The 70-200II is not better than the 135L for IQ at any aperture.
True...but nor is it worse (Klaus at PZ gives slightly higher numbers to the 70-200 II across the frame at most apertures, although probably not real-world relevant). That being the case, from an optical standpoint the only benefit to the prime is that it's one stop faster. That can be very important in some situations, but the zoom certainly wins on versatility with no sacrifice of IQ.
I would appreciate a 100-400 2.8 :-)
You must be a back surgeon.

Did you even look at the lines? Its pretty obvious.
That the 50/1,4 is better yes, and you can se that also in photo zone measurement figures at 2.0 , 2,8 etc etc
You have rejected four recognized test sites results concerning 50/1.2 and resolution compared to 50/1,4.
Then you have have mixed up the results from
As you can se, 50/1,2 are less sharp than 50/1.4 at F-1,4
The center is better on the 50L and there is less haze in shots i've taken from the 50L vs the 1.4.
over all better resolution with 50/1,4 at 1,4 and 2,0 than with 50/1,2
