No, I am not looking forward to it either. I always worry that something will go wrong, particularly if it is fixing something that isn't broken. Club members were offered a beta version of this back in October and I downloaded that with no issues, hoping that I had gotten it over with then and there. Unfortunately the version number of the beta is different than the one mentioned in the link I gave above so it's looking like I will have to update yet again.
Mad, I think when the update is available it will just automatically start installing when you begin to download a game; at least, that is always the way that it has worked in the past.
