After seeing Superion a couple months ago for June (with Slingshot), a Menasor was expected to follow it, and hopefully with a Wildrider as well.
Scans of the current Figure King magazine from Japan has given us a very small tease of Menasor, and the left leg is definitely NOT Offroad.
From what I can tell, it looks like the Dead End mould, but is so obscured, I can't be sure until the official images are released later.
No release date yet, but probably August-September, as it was revealed a couple months after Superion.
For now though, it is something for Combiner collectors to weigh up as the Wave 2 Hasbro combiners are yet to come here, and still struggling to show up outside of Asia so far.
The scans also show us the three Adventure toys that come out in April and three Q-Transformers (looks like QT-18 might have been held back from March), and the Kabaya D-Collection models... but with all the excitement over Tracks, the rest of the items on these scans were mostly overlooked.
