I agree with Trev's sentiments. Meanwhile, in the land of facts...

I've never seen a year so busy for MP collecting! These toys naturally come out at a slower rate because they are a more quality-focused line over the mainline stuff. Just looking at the crazy degree of engineering that was poured into MP Ironhide is mind boggling. That level of technical wizardry doesn't happen overnight. And remember that this the same creative team who are also simultaneously working on other TF lines, such as Combiner Wars, RiD, Titans Returns etc. It's not as if there's a team who are solely dedicated to developing MPs and nothing else for TakaraTOMY.

Guess they can't make everyone happy.
