I dunno man, CDPR have lost their sheen a little bit for me. Not specifically because of Cyberpunk, but just their general behaviour as a company.
I hope it's good, but I'm not going to count on it. Also I bet they won't carry on the same customer loyalty stuff they did before - I got a preorder discount for Witcher 3 for owning 1 & 2, and the game was eventually updated to include all DLC and morph into the GOTY edition.
Also, the Witcher storyline was pretty well wrapped up after 3. I worry this will be more of a cash grab than anything else.
