Pinside and new games are super predictable. New game is announced, its the best thing ever. Game comes out and the complaints begin. Newer games are announced, game is now old news. Code is shallow so game goes down in value. If its lucky it gets code updates to the point where it is considered an amazing game again.
As for OP's argument WOZ didn't devalue 90s B/W titles. There is a massive difference between it and those. Not really a massive difference between this and WOZ.
Exceptions are games that get short runs and have interesting stories, see TBL, BBB, Alien. Not games that are cut short because they just failed to sell, see FT, CSI, NBA, etc.
