probibly but who knows they might do that. they did it with other lenses in this line. Like the 28mm
I don't know if they will now. When the 28mm and 40mm lenses released, the LTM was launched
alongside the M versions; it didn't follow later.
I suspect that Voigtlander looked at the sales of the LTM versions and figured that there's not enough demand to justify doing two versions, but I'd argue that (presumably) underwhelming sales of the LTM versions of the 40mm and 28mm lenses would be because:
a) 40mm is a weird focal length, and there are basically no 40mm finders available anywhere, so it's a tough sell for a lot of LTM users
b) the 28mm is really just a minor upgrade to the classic 28mm f/3.5 Color Skopar, which most dedicated LTM users are likely already hoarding (I know I am)
c) the M mount version of these lenses took sales from the LTM version; selling just the LTM version with a pre-packaged M adapter (a la Light Lens Lab) would have been a better (and simpler) move. Hell, it would have made more sense doing that for the 40mm version, as they could have packaged it with both the 35mm and 50mm adapters, so M users could choose which framelines they preferred.
Also, on a lesser note, the fact these two lenses were available in LTM but
didn't accept commonly-used A36 filters that most LTM users will already own was a
really dumb move. I hope that the included hood on the new 35mm f/3.5 Color-Skopar - which appears to be styled after the A36 FOOKH hood - is an indication that they've not made that mistake again.
