If CDPR is smart, they should keep releasing updates, small or big, in order to keep players interested in the brand until they officially announce the next Cyberpunk game.
Here's a fun counterpoint - the more CDPR keeps releasing patches, the less I'm interested in buying Phantom Liberty 'cause Cyberpunk's mod infrastructure is a Lovecraftian mess and I don't feel like wasting a couple of hours updating every time devs tweak the stream angle for an NPC pissing in a corner.
This is the company that released C2077 early to make more money, only to lose billions more in stock value than they ever sold.
No, this is the publicly-traded company that released CBP2007 as late as they could in the face of stakeholder pressures. The fate of their stock value was sealed much earlier, due to poor core design and a mismanaged development, a couple more months wouldn't have made a difference and there's only so many times you can tell investors and creditors "next Friday for sure, bro."
