A bit of clearification here, from a new member none the less
There wasn't a large quantity sold. Both sold aprox 5% of their holdings. At the same time there has been two cases of insider buys from one of the boardmembers.
This isn't Remedys final stand either. They have a healthy cash position, and no need for external money to produce their next game. They have easily funded Control (20-25MEUR budget) with publisher payments from 505 games and WFH payment from Smilegate.
As for Sony buying, it's doubtfull. The studio went public two years ago to become a more independent studio, and there are very few publicly listed studios that have been bought by bigger studios, the only one i can think of is DICE.
But i do believe something is up with Sony, most likely a exclusive deal for one of their upcoming games.
Also, pre orders are going OK, based on amount of reviews on PSN. I'm guesstimating sales are in the 80-90k range as of now (on PS4).
On amazon the XBO and PS4 version are in the top 10 sales of their category.
