While I don't think I like the gap, I guess it's necessary to get enough room for the feet to move up and down –and even to open- in fighter mode.
It does look like Bandai has addressed all the shortcoming of the DX 25. And now they're just around 30% of the molds away from a V.2 VF-25. I mean, all the mechanisms seem to be ok, they only have to change the head, chest plate, back plate, wings, thigh kittle and outer side of the lower legs and fins. Come on, Bandai, just do it!
