Who are these "legit gamers" and what makes them legit?
I'm not going to argue whether the game is a 6, 7, 8 or 9, but someones decision to purchase a game probably isn't going to impact anothers view of that game.
Many of the reasons this game was scored so badly and people refused to buy initially was mostly because of these glaring issues. If they are fixed, which would obviously improve the game, obviously scores would go up (actual scores may not change as many do not re-review games), but the consensus of the game would change and maybe these "legit gamers" would then purchase the game since it is now improved.
Personally, I hope the reviews do not change (at least the published ones). The way I see it is if scores and reviews are important to the development team, then this should be a lesson learned that their initial product needs to be of higher quality and that a patch should only be necesssary for minor tweaks and updates and not to "finish" an incomplete game.
