Rumour: Modern Warfare 2 Street Date Broken?

OXCGN hears that another retailer may be releasing a game early, this time MW2:

"It seems that over at the Australian Xbox.com forums there has been some speculation that Activision's Modern Warfare 2 could be on the shelves as early as this end of the week according to some forumites.

It seems that Big W has spoken to a few of their customers in store notifying them that they can stroll into the store as early as today (Thursday 5 November) and pick up their copy."
