I just wanted to say that the 12-60 has really good resolution.
The best lenses of Olympus are easily on the level of Canon and Nikons best. For example the 150mm F2 or 300 2,8. I don't think that the Canon 600mm F4 is better compare to 300mm 2,8. Ok you have 1 stop less noise on a 12Megapixel FF, but I guess you can build better lenses on smaller sensors. FT needs only half the diameter for the same angle of view so there is room for better optics or even better F stops.

I think you're looking at it from the wrong angle... if the maximum amount of pixels information in the shot is 12MP (let's assume 12MP because 4000x3000 is nice), considering a FT sensor is 17.3mm wide, the 12-60 roughly and theoretically resolves 4000/17.3=225 pixels per mm (like 115 lp/mm). To get a 12MP image from a 36x24mm FF (12MP 3:2 = 4242x2828), all you need is a lens to resolve 4242/36=118 pixels per mm (like 59 lp/mm)... which is not that difficult.
So, yes... if you put a 59lp/mm lens on the 12MP FT camera, it'll look like crap, but that's all you need on a FF to match the maximum detail possible from the FT camera.
Plus, if both sensors produce images that are 12MPs... a FF sensor pixel is 3.84x the size of 1 FT sensor pixel. The almost 4x size means a nearly 2 stop advantage in noise.
Sadly there are no FF EVILs to even the playing field. So, smaller formats win because they have little to no competition from FF.
