Hasbro confirmed to Yakface that this wave is, indeed online only:
The last Vintage wave of 2012 will be released online only. The figures will be available on Amazon, Entertainment Earth, Big Bad Toy Store, Brian’s Toys, and other specialty shops. The figures are listed below.
Obi-Wan (Clone Wars)
Naboo Pilot
Aurra Sing
Gungan Warrior
Nien Nunb
Royal Guard
Republic Trooper (The Old Republic)
Orrimaarko (Prune Face)
Oh well, better exclusive than cancelled. Amazon put up the figures individually for $12.99 each, so it may be good to check them out if you don't want the entire case. I may get at least one extra Royal Guard from them.
