Official Support and shared windows/linux version?

Hello,

I couldn’t really find a definite answer to that, so my question is if this linux version will ever receive official support in terms of bugfixing especially.
In the current state it is far for me to use the unofficial linux version due to several issues that look to stay.
And if it might become an official version one day, and you already have the windows version, will the Linux version be handled completely separate, regarding support, updates and even price, or will it share the same features as the windows version?
I’m asking because it seems that even if there will be official Linux support one day, it will be quite a bit in the future and I thought of buying the Windows version meanwhile so I can then fully switch to the Linux one when it gets officially released.
