Here they are boys and girls!  The World of Warcraft Cataclysm Leatherworking Patterns!  These patterns can be purchased in the Twilight Highlands from Threm Blackscalp (H) or Misti Merriweather (A) for the super low price of 10 x  Heavy Savage Leather.

Note: Upon Cataclysm Launch a number of Epic level 525 pieces were incorrectly labeled as requiring 425.  These will still show up as “Craftable” when you view them in the Vendor, however, if you try to lean them before reaching 525, an error will occur.  These patterns are appropriately listed in this table as requiring level 525.
