A user of Starblight.de forums found the YOTH Starscream in a local TRU Store in Kamen, NRW. The Price is 149,99€ and the figure is also listet in the online shop: Transformers - Year of the Horse, Supreme Starscream Platinum Edition - Hasbro - Toys"R"Us Full news (in german) at Starblight.de: Transformers Platinum Edition Year of the Horse Starscream in Deutschland veröffentlicht! » Starblight.de
I already wasn't interested but for 150 euro's ($ 200) I REALLY am not interested. But on the other hand, I will consider this a positive sign that TRU europe might also release YotH MP Optimus. Although, if that will also cost 150 euro I'll probably e-bay it if I really want it.
