I thought the preorder would start on the 13th. The bags will be listed in the TB website on the 6th.
Edit:
Quote from Darcy's timeline post:
August 6th
Pages for the Synik 22 and 30 go live. The pages will have an abundance of information — description, specs, photos, videos, an FAQ — to help you decide whether the Synik is the right bag for you (or not).
August 13th
Pre-order opens / remains open until 08/20 unless either size of Synik sells out.
August 20th
Pre-order closes.
Late October
Pre-order Syniks ship.
