If you had an account on the old Bungie.net system and want to link it to a Passport account so you can keep your nickname, you have been warned: your last chance to do so is before this Sunday at 5 PM. After that, the non-Passport accounts will be deleted. Check Achronos' post at Bungie.net for the details.

Editor's note: this probably means that Bungie is a step closer to revealing what they've been working on for the new Bungie.net.
