Crossroad again - 85mm f1.2 or 5dmk2

I have the opportunity to either buy 85mm II f1.2 and stay on my current 7D for some time or move entirely to 5dmk2 and (maybe) buy a 85mm f1.8.

I mostly do headshots and head & shoulder portraits of babies, kids and adults. I'm obsessed with good and clean bokeh.

My mind was blown away with the results of 85mm f1.2, even when used on higher f-stops. It's just breathtaking.

I'm aware that just by moving to 5dmk2 would also mean better bokeh and shallower DOF with my current 50 f1.4 and other lenses. But I'm also aware that buying a 85mm f1.2 is a very long-term investment.
