I believe the YF-19 was designed with the assistence of Studio Half Eye.
When I first saw the prototype, I was very impressed with the sculpture.
But when it finally came out, there was alot of problems with fitting certain parts.
Glad they decided to redo everything
Actually I hope they reduce the die-cast content abit and re-enforce the joint\moving areas with die-cast. The 1/48 had a nice balance for me My opinion there.
