I just had a quick questions, what other Generations figures are there? I currently only have Armada Starscream.
I'm not sure how much luck you'll have finding any of these, but going back as far as wave 1 of the "Thrilling 30" stuff, you have: Wave 1 - Legends class Optimus and Bumblebee, Deluxe Orion Pax, Trailcutter (based on G1 Trailbreaker), Bumblebee and Megatron, Voyager Blitzwing and Springer, and Titan Metroplex. Wave 2- Legends Megatron and Starscream, Deluxe Thundercracker and Hoist, and Voyager Sandstorm. Wave 3 - Legends Swerve and Cosmos, Deluxe Skids, Dreadwing, Goldfire and Waspinator, and Voyager Rhinox and Double Dealer Wave 4 - Legends Tailgate and Skrapnel (based on G1 Shrapnel), Deluxe Scoop, Mini-Con Assault Team (Wind Shear, Runway and Heavytread), Skywarp and Armada Starscream, and Voyager Whirl. Wave 5 - Deluxe Rattrap and Tankor. There's also Legends Gears and Acid Storm, Voyager Sky-Byte and Roadbuster and Leader Jetfire due to come out, but when they'll start appearing I don't know. As for stuff that'll be coming out later this year, we're due to get Legends Cliffjumper and Nemesis Prime, Deluxe Windblade, Crosscut, Nightbeat, Jhiaxus, Arcee and Chromia, and Voyager Brainstorm. In 2015 there's going to be Legends Bombshell, Powerglide, Windcharger and Thundercracker, Voyager Optimus Prime and two Leader Megatrons, one based on G1 and the other on Armada.
Not the old IDW deluxe wave but some stores have went back to stocking those wave 1 and wave 2 legends since most WM didn't put them out when they were supposed to.
