Hasui felt the same that's why we haven't seen Megs yet.
I'd really love to see Hasui's interpretation of MP Megatron. He perfectly followed through with the same cartoon-and-toy-accurate "Masterpiece" aesthetic Kobayashi had created and also managed to blend in his design style. Kobayashi was brilliant (what a talent! his first full-on design work with Takara after just graduating collage was Car Robot Speedbreaker, 'nuff said) but personally I prefer Hasui's style better now and I think he is perfect for the new MP direction. Looking at the differences between MP01 and MP10, I guess he will do whatever he can to give us a comlplete gun mode with all the beef-up parts. And with the new scale this time we may get a P-38 only slightly bigger than the G1 toy/real thing.
