Probably not, as I would assume like most reviews they are a slice of the game in the moment and many can't/don't want to return to re-review. It's just interesting seeing a lot of the user reactions now bringing different perspectives, which is always expected come actual release, from the reviewers.
Heck, I was a game's journalist years ago and there is a certain rush to get the game reviewed, especially a big names title. It's just difficult to ascertain the true offering of a game until it has been played by yourself, if it interests you enough. That's obviously a reviews job though, to give you an idea of whether it may suit you or not.
