At this point, only the 599 GTO is getting the US rebox. I know this because Revell said so. I brought them my Italeri 250 SWB to see if they could clip it into the US Box, but it could not. They RoG didn't make the deal with Italeri anyway.
I still have, unbuilt, a lot of the Italeri Ferraris such as the 275 GTB and GTS, 250 SWB, 250 California, etc. So Revell could actually look at the sprues to see if there were cut points that be used.
On the SA Aperta, since only 80 were (offically) made, it was deemed less desireable to US Box than the 599 GTO. They could always change their minds. But that is where they currently stand.
I also made a case for them to get RoG to do the F12 Berlinetta and Enzo replacement. I know Fujimi is doing the F12, but we saw the quality difference on the 458's. I have a Fujimi F12 on pre-order and will evaluate it when it shows up.
