I'm convinced if this game ever does "finish" DC will just create a sequel to Summertime Saga in order to farm even more money, that is if their next game that hasn't even been revealed yet doesn't farm enough money on it's own but knowing DC he'll just milk that as well.
The Tech update is to rewrite the code in hopes of faster updates but we all know damn well nothing is gonna change, the passion to actually complete this game has gone out of the window a long time ago and has been replaced with greed. Red Dead 3 will release before this game even finishes.
