Don't know if this is old news yet, but just saw 2 new listings for both the new MP Thundercracker and Skywarp. Obviously these were bound to come out. Starscream's price wasn't as bad as I initially thought it was going to be ($275 US on TF Source).
Here's the links for both Thundercracker and Skywarp on Bababobo:
