M300GT rises more and more by the NEW body appearance. …dependence.. ?Mi and ..turning over.. wing are different for a moment. Sta is different though the wing shape is also different.
The wing here is an optional and GT wing of the sale schedule (tentative name). Because it is a straight typing of the body, detaching the body can be facilitated.
Z body and the GT wing will shortly be sale schedules. Formal announcement such as prices and release dates : again later.
