If I buy on GOG, will the future Linux version be available to me?

Hello,
Sorry for a seemingly stupid question, but it needs to be asked given the history of GOG. It would seem that a lot of games that have Linux ports on steam don't always have a Linux port available on GOG. Given that I much prefer to buy in a DRM free format, What are the chances that X4's Linux port will be on GOG? I've held off on buying until I can get this answered. Unfortunately due to the problems of windows 10 (spying, instability, updates that break things, etc) I've started migrating my main machines to Linux. My laptops have had Linux on them for many years, and I have enjoyed X3 and X Rebirth on them over the years. Hoping to continue this trend with X4, except on my main desktops as well as my laptop.
