The current shipping embargo of the Fujifilm GFX is February 23. Of course there can be changes anytime, mostly depending on eventual last second firmware issues. But also in that case, Fujifilm will work hard to ship the GFX before the end of March, when the Japanese fiscal year is ending and Fujifilm would like to share some positive GFX sale numbers with its investors ;)
The shipping embargo rumor is for USA, but it should apply to all the world (maybe it will ship even earlier in Japan).
Recent rumor confirm, that the price for the body + lens (63mm) will be of $8000
