Depends on when you ordered it.
The full details are here, but I'll quote them:
"If you pre-ordered, and have confirmed your address, your estimated ship date is as follows:
Pre-orders placed before April 30th, estimated to ship by Aug 31st (4961 pre-orders)
Pre-orders placed before May 31st, estimated to ship by Sept 8th (5368 pre-orders)
Pre-orders placed before June 30th, estimated to ship by Sept 15th (4116 pre-orders)
Pre-orders placed on or before July 22nd, estimated to ship by Sept 22nd (3883 pre-orders)
New pre-orders placed on or after July 23rd are estimated to start shipping in October"
EDIT: @senkun: Wow °_° I never knew that, they must be having a ton of shipping problems... Well anyways, I think that this will be the final update because these shipping times are already SO FREAKING LONG!
