Cancelling is abit over dramatic if its just about delays in release. I personally have the patients, my only gripes are with the colour and head articulation. I think you should wait it out and if your dissapointed when it arrives then sell it on for profit, no worries!
Im overall a little dissapointed with the MGS figures. They all have these simple issues that stop them from being truly great. Like playarts Snakes face sculpt, foxs colouring and lack of open mask HTs Naked Snakes suit. For me the best one is Play Arts BigBoss since hes actually accurate to the character in PeaceWalker, and i don't even like BigBoss!
