PC
Xbox One
PlayStation 4
I would love to play on PS4, but based on the informations we got I chosed to sign up for PC.
I don't have PlayStation Plus to play online, and most of my friends that have a PS4 (they are rare) won't play this game. So I stick with PC and hope that it won't be too heavy, so I don't need to upgrade my graphic card. I'll play with controller though.
Also I think it is easier to give feedback to the developers with playing on the PC.
If it will be possible to test more then one platform I would go for PS4 AND PC, but I highly doubt that this will be possible.
I somehow have the feeling that the game will be out on PS5 and the next xbox but I can hardly imagine what they would be like, just some extra powerful xbox one x but I think they need some time for the price to drop compared to one X because the the one X is kind of powerful enough but they need to change architecture to be able to go to the next level. I have a PC and a One S so I will probably buy it on the One S if it come out soon enough, otherwise maybe PS5 or next Xbox. If I haev a steam link and a good network, PC on TV version would be the best
