Revoltech revealed one certain Mandalorian at the Winter Wonder Festival in Japan...
Whilst these are unpainted, they could just as well be a blue shot protoype and white prototype Boba Fett. (Maybe expect that as a future release!) 5400 YEN is approx $46 USD so a fair price when compared to the recent Revoltech releases. No other info at present and images via TheFwoosh (Their source not credited). A Revoltech Delorean and Pacific Rim figure were also revealed via the excellent Infinite Earths blog.
I'll certainly pick this up and review closer to the time. Do you want another Boba Fett Six inch figure? Would you pay this for one even with improved articulation?
