We will look if we can bring doubleshot cyrillics with it, but this is not a promise. If doubleshot cyrillics are too expensive then it will be just latin... We are checking right now the pricing for cyrillics.
Please keep with doubleshot keys if you must go the GMK route. This is mad unfortunate. I think we might have a hard shot if this goes to Massdrop as a GMK all in one kit with Cyrillics and even all Latin for that matter. Its a nice color way but like you said, it may not have carbon's demand especially since GMK would need to make custom color keys. Its been in IC this long, what's another few months? SP is still a good test for demand, and Yurican always be run again in GMK. I'm afraid if it goes to GMK first and demand just can't hit it, it might stall.
I mean if looking at the current set running on MD yields insight, its obvious that the real bulk of the orders is in base + mod + numpad. This tends to normally be the case. With that in mind, GMK makes it all or nothing meaning that unless we really hit strong positive demand, users may bulk at a initial $125.00 price point plus shipping. 80% of the buyers don't typically purchase the child deals, but the child deals together add to the base kit purchases which lead to more buyers due to the "lower price points". Still, Yuri could hit 250 MOQ and even more, but it would be nice to test the waters with SP and then go to GMK. A equivalent SA profile from SP with base, mod, and numpad kit is $95.97 at its lowest (MOQ=250) or $119.97 at its highest (MOQ=1). GMK normally has a MOQ of 100 or failure.
SP brings a lot of pent up demand after the first round which could turn into GMK sales for round 2. 374 votes currently tallied for the Yuri SA profile on MD vs 1517 for the currently active SA profile drop. It might be worth putting up a poll for GMK once the GMK renders are due back and see where it goes from there.
In the end its OP's decision and what profile would be best suited for the color way chosen.
