Official copies will not be released until the official release day which, last time I checked, WAS NOT Monday 7th November, Tuesday 8th November, Wednesday 9th November or Thursday 10th November so until I play the official release of the game I will not believe any reports of "issues" from people playing leaked copies!
Are you being intentionally dense?
First off - Time zones: It's already 11/11/11 in some places
Second - Several stores (Most in Northern Europe) ignored the Release Date, and started selling the games as soon as the shipments arrived (which was sometime last week)
Third - Mailed Pre-orders. Some people get their game a day or two early because the mail is unexpectedly fast.
No pre-order or Shipping company wants to run the risk of pre-ordered games arriving
late, so they err on the side of early.
