TFW2005 member Phynxes found wave 2 of the Siege Voyagers (Starscream and Soundwave) at Müller in Cologne-Kalk, the same store the wave 2 Deluxes were first discovered just a few days ago. Meanwhile, I didn't find them at the Müller store in downtown Dortmund (they were presumably bought by NTF-Archive member PlexDirector, who found them there yesterday), but I did find WWII Bumblebee and Barricade from wave 5 of the Studio Series Deluxes, which means German retail possibly skipped waves 3 and 4 (they might still show up eventually, though). Lastly, I also found Cyberverse wave 3 Ultra Optimus Prime at Müller in Datteln, though I didn't see his wave-mate Slipstream at any of the stores I visited today.
Nice find! Now, does this Starscream have the pins in the chest plate (updated version) , or is it the original version where the chest / yellow canopy tends to pop off?
More findings of these (including the rest of Studio Series Deluxe wave 5): Cyberverse Ultra Optimus Prime at Real in Bochum-Wattenscheid. Again, no trace of Slipstream. Siege Voyager Starscream and Soundwave plus Studio Series Clunker Bumblebee, Sideswipe, Crankcase and Barricade at Spielzeug-Paradies Wagner in downtown Bochum. Starscream, Sideswipe and Crankcase also at Müller in downtown Gelsenkirchen.
