I also don't think every single issue will be fixed. They'll keep doing patches and updates to where it's playable and largely bug free, but it won't be cost feasible for the studio to keep at it, especially with the fact Halo 5 release is coming.
It's not even the bugs personally that is the worrying problem, but the player population and playlist management especially after Halo 5 beta. Maybe if the game is bundled free down the line, but I think it's going to be tough. Even if matches are found easy, will probably be a huge disparity in ranks/skill.
