Olympus 4/3 mount 50 f/2 - worth it?

I have been using Oly stuff since the old E-10 days.  Over time I acquired some different lenses.  From my old 4/3 SWD glass I still have the 50-200mm f2.8-3.5, 12-60mm f2.8-4, and the 50mm f2

With the E1MarkII, it has brought new life back into these with the PDAF and I have my fast AF back again.  I also have some of the new micro 4/3 glass, 12-40mm f2.8, 40-150mm f2.8, 25mm f1.2.  I might part with the old 12-60mm and 50-200mm but not the 50mm f2.

I enjoy portraits with the kidos and of all these lenses, I gravitate back to my old 50mm f2 over and over and it is on E1MarkII much of the time.  I tried the new 40-150mm f2.8 pro and the bokeh is too nervous.  I have the 75mm f1.8 on order and looking forward to it.

My thoughts on the 50mm f2, with the E1MarkII, it is still my go to for head and shoulders.  If I am in a tight area or need width for group shots, I love the 25mm f1.2, but go back to 50mm f2 on one or two subjects to keep facial facial features less pronounce (again looking forward to trying really tight shots on the 75mm f1.8).

So if you have the 45mm f1.8, that's a tough call.  I don't have the Oly 45mm f1.8 and don't have any interest while owning the 50mm f2 and PDAF E1MarkII.  The only way I might consider shelving my 50mm f2 is with the 45mm f1.2 but I haven't been able to justify the cost for what I would gain.. yet.. lol.  But the f1.2 primes are amazing.
