Korg and Roland synths are out of discussion because of the restrictive policy that those companies have about emulations of their synths.
Oh come on, man, if Mg is just plain dazzled by the recreation of the MiniMg, I think Roland would be too if their name is linked with the product. Mg even supports the Arturia version!
With the quality of sound Arturia makes its SW-synths, the Jupiter 8 just HAS to recreated in software cos its getting so rare.
Mg do not do software themselves and seem not to be interested in doing software, while Roland want to establish their own software platform with
VariOS, for which they have done two very bad and un-accurate 'emulations' so far, namely the VariOS-303 and the VariOS-8.
They have already told quite a few small companies who did Roland emulations to dicontinue their products (e.g. reFX for the JunoX2); the same for Korg (e.g. the reFX Nexus, which was supposed to be a Wavestation emulation, then turned into Xphrase).
With all that in mind,
I guess yours is just wishfull thinking! Like I said before: Arturia would have to be quite clever to on the one hand
market e.g. a Jupiter-8 emulation as such, but at the same time
not name it similarily and
not make it look like a Jupiter. OTOH, since they included it in the poll, what do I know? However, the poll was set up before Roland started searching around the net for companies they could tell off...
