I like the 48s more, but if yamato were to start releaseing things on the same level of detail and at the same height as the current 48s, I would not care of the scale.
I think the reason Toynami went with the Book boxes, is due to the fact that they knew it was a inferior product to the Valks already available. And in order to get buyers, they hyped the MPC, with the MPC stuff, the boxes and LEDs.
There is a difference between books and TV shows. Books are not limited in ways such as effects and set cost. I think this may turn out bad in the long run.
