MHG-XPRO3 — is it Arca Swiss compatible?

Just saw that, along with the x-pro3, Fuji announced a new grip (MHG-XPRO3). There’s only one picture (Please login or register to view links) for the moment, but it looks like it doesn’t has the “indent” for use on a quick-release Arca-Swiss compatible tripod head. The press release doesn’t mention it either. Would be a shame.
Anybody seen the grip IRL?

thanks!
