When I log into Gox i see a red message just above the buy/sell tabs, "Sending a WIRE TRANSFER to your account? The SWIFT code for depositing to Mt. Gox has been changed by our bank. Please find the new information under the "Funding Options" tab. Transferring using the old code could cause your deposit to bounce-back, possibly incurring fees at your local bank. "
Maybe far fetched but i think they have issues on the level of governments on their shoulders. A new SWIFT code suddenly could also mean that those who tap SWIFT transactions want it to be easy to track every transfer to Gox using a unique SWIFT code.
