1. This franchise is cursed isn't it.
2. The 'good' (sad) endings for Cyberpunk seemed ambiguous as to what happens to V, it almost seemed like they made it that way either for an expansion or sequels in the future. Basically the way I see it, the 'secret' ending may end being canon, but then there are only two possibilities: A. Either he/she survived with some new advanced tech or B. V is loose in Cyberspace pretty much exactly like Ghost in The Shell.
I could see them re-adding stuff that clearly got cut before the deadline in a Director's Cut; i.e. apartments, cutscenes, the original default FemV. I'm not so sure they would be able to change story stuff.
I think people will refer to Cyberpunk 1 like Witcher 1, a cult hit. And down the line people will reference Cyberpunk 2 or 3 as the 'goat' or whatev.
