For those interested, RK have opened up pre-orders for the following:

Generations 2011 Wave 2 - Kup, Scourge, Thunderwing & Cliffjumper
Reveal The Shield 2011 Wave 2 - G2 Prime, Perceptor, Wreck Gar & BBee

They have been slow recently with listing some of the Hasbro stuff as BBTS and TF Source have had these listed for pre-order for awhile now.

RK's shipping is cheaper, so for those that haven't placed their pre-orders yet, time to go for it.
