It's certainly well past time we got a 1/48 YF-21, considering how long the YF-19 has been around. Granted the YF-19 is a much more popular Macross YF/VF, but it's really a good time to finally add the 21.
And considering how many different VF-11 variants Hasegawa has released, I'm hoping they do jump on the batroid version soon. The armored version would be super cool.
I see Mercy Rabbit is doing the art for the VF-0S gerwalk. Should be good.
