Does anyone know iif GoG will eventually get this or if the 2014 GOTY edition will be it?

Good question, would want to know that myself.

Same here. Would really like to know if it is possible to install the latest update.

I'd also love to see 2.0 here, but since AFAIK it has EAC (Easy Anti Cheat) on Steam and disabling it via mod seems to disable singleplayer achievements, too, I doubt that we'll see it here.

A shame, I'd probably buy it again here although I already have the 2014 version, but not on Steam. So, no 2.0 for me and no extra money for the devs.
