Snake,
The Japanese just got their first Longbows about 2 months ago. They're starting to license-build them over there now. In fact, as soon as the JGSDF got their first Longbows, Hasegawa released a boxing of those markings! I believe they are the equivalent of US Lot 6 AH-64D's. Not up to the absolute latest, but pretty damn close. They're also probably gonna put a bunch of new avionics in there too.
Alby, as far as I can tell, the rear cockpit is pretty much the same as earlier Lots. I'm trying to find better shots of the MPNVS turret. Modifying the kit's PNVS is rather rough going. Otherwise, its coming along really well.
