No ETA yet but this was just announced by Raymond on ARC a couple of hours ago.

A 48th scale Global Hawk recon RPV has a wingspan of 82cm (32 inches).

Also for the small scalers out there the 72nd NATO weapons set should be available at Lucky Model by the 1st of July 2010
It isn't on pre-order yet on LM but it should have IRIS-T, Harpoon/SLAM and GBU-39 Small Diameter Bombs
When it's up for pre-sale I'll link it
