UPDATE 9PM BST: CD Projekt Red has since downplayed the "few days" proximity to me. "PS4 Pro and Xbox One X: both technical updates are coming," senior PR manager Radek Adam Grabowski told me. "More details about them, including the exact moment when they will be released, are something we are going to announce when the right time comes." Will it be "just a few days", then, or significantly longer?
As to the '100 people working on Witcher' intrigue, Grabowski clarified the comment referred, as expected, to the number of people working on Gwent.
