The scale charts are a load of bollocks, half the time the animators at Sunbow didn't even stick to them from one scene to the next so the fact they're now being used by some as this unquestionable bench mark for the Masterpiece line post reboot is questionable to say the least.
Besides which, MP08 and MP10 do work....IF you consider their scaling to be based on some of the original G1 comics as they were often depicted as being of a similar size.
Failing that just put Grimlock on an acrylic riser to raise him a couple inches, stand a few smaller characters in front to obscure his legs and you get the same effect.
You could even remove MP10 from the equation entirely and use Faith Leader, that's the approach I took as I can't stand MP10's robot mode.
If Grimlock 2.0 was made to the same scale as the Almighty Scale Bible the pricing would surpass anything else we've seen so far and cause even more whining than we already get from skint/cheapskate fans with entitlement issues.
I also think any expectations of a complete set of MP Dinobots from Takara are unrealistic unless they suddenly become REALLY popular in Japan. Aside from Grimlock, they don't seem to give a crap about them.
At present a new Masterpiece Hot Rod is more likely from Takara than a new Grimlock or more Dinobots.
