I have the 50/1.4 Otus ML (E-mount) but not the 85/1.4 as I'm sensitive to size, weight and price and anything bigger than the 50/1.4 is going to be challenging on my A7CII and other compact camera bodies that I prefer. 50/1.4 ML is the most expensive lens I own today and anything more costly than that would be a bigger stretch as well.
I would have been more interested in 28/1.4 as well since I'm a 28mm fanatic, but since we now have CV 28/2 and 28/1.5 I'm not feeling the need for more options as much as before.
A 35/1.4 Otus ML is still interesting to me but as I have CV 35/2 AL, 35/1.2 SE, 35/1.4 classic and Sony Zeiss 35/1.4 + Sigma 35/2 (+ a bunch of more exotic options), I'm quite well covered there and I don't love 35mm FL as much as 28mm. If it's the same size, weight and price in Japan as 50/1.4 Otus ML, I could still consider it but perhaps not immediately at launch. Will be interested in trying one out at CP+.
If it's introduced at CP+ for the first time, I think it would be officially released in May or later (Cosina already plans to release 40/2 Septon in March/April and I don't think they'd schedule a new Otus at the same time due to production constraints etc.).
