To be frank, i honestly think Larian should make a stance to not port or make it available to PS4. If they are holding content on their platform and forcing PC gamers to purchase their hardwares and pay subscriptions, why should PC games make available on their platform?
These corporate giants has been constantly trying to kill off PC gaming solely for the purpose of their own benefits so that they have part of their market share in gaming entertainment. PC gaming is not dead in anyway if you look at the MOBA like LoL and DOTA (which currently having TI4 International matches in US).
Console gaming has nothing more than trying to kill off PC gaming. Do you see MOBA or any RTS in E3? It's all about HYPE and false advertising (demonstrating next-generation games on high-end PCs) while the end-product that land on gamers hand is no where in comparison.
If console gaming STOP these exclusive crap, then by ALL means do release the game to consoles (i'm not selfish like some Japanese corporations).
