CDPR has made it clear they don't want to officially talk about Cyberpunk 2077 details until they've started its promotional campaign leading up to release. So therefore, there has been no reason to use the official twitter page to promote anything ahead of release, such as development updates, game related interviews, etc.
It seems to me that CDPR doesn't want to outright talk about the game regarding any real concrete information yet, but they want to get the internet talking and drawing attention to the game and social media to get as much of their audience ready before the eventual huge reveal. Therefore a little buzz word *beep* was posted and almost every major video game news website jumped on it immediately and has already drastically boosted more attention and the word is spreading fast from that simple post.
Thousands of new twitter followers in one day, I'd say CDPR's methods are working.
I think *beep* is the ON button, the boot up sequence. Now to anticipate what's next...
