Update: After several hours of googling and soul searching, I've decided (unless somebody soon sways me otherwise) to buy
1. Olympus OMD EM1 II (Coming soon. Sony has a new FT 20MP sensor, so it shouldn't be long now for a Mark II OMD EM1)
2. Olympus ED 40-150mm F2.8 lens
3. Olympus MC14 1.4x teleconverter
4. Olympus ED 300mm F4 (coming soon)
...
In several hours of Googling,
why did you dismiss the seemingly Built-For-Landscapes
(your stated interest) Oly E-M5 II ?? --which, in reply to
your (overly, IMO & others') dismissive "only 16mpx", can
claim FORTY (4-0) mpx, topping those mere 36mpx guns
of yestermonth! (But I've not seen you make a direct reply
to the challenges re "only 12 / 16 mpx" vis-a-vis actual output,
voiced here by many users.)
Moreover, I don't know where your Googling took you,
but in less time I found on
www.43rumors.com a recent post
in which
--nevermind what Sony might have just done (or Pany
just released in their GX8)--
the stated resolution for the E-M1's upgrade is, to use your terms,
("only") 16mpx --re-using same (Pany) sensor, I presume,
as was the same Sony-made 16mpx one re-used in E-M5 II.
(And which is one that Lula's BCooter continues to see as giving
best colors, of maybe nearly ALL of his cameras (which includes
1DX & S2?) --but certainly vs. E-M1 & 1DX & his testing of the
earlier Sony A7 body. But maybe that's a fashion photog's and
not a landscaper's preference --I've not seen ANYonElse concur
in this particular distinction!?)
And with perhaps some rush of the Gotta-Get-The-Latest... group
from their still sparkling E-M5 II's to -M1 II, you might even get
some bonus in (barely) used pricing!
Ming Thein, who had some issues w/Olympus both of technical
and *political* sort, gives a full review of mkII version now

http://blog.mingthein.com/2015/05/21/review-olympus-e-m5-mark-ii/Btw, I do NOT see mentioned in the E-M1 rumor anything about
the sensor-shifting 40mpx option; that, I'd think, would concern
you much.
