I saw this on the Hyperscale website just a few minutes ago:
36501 1/48 TYPE 95 SMALL SEDAN "KUROGANE 4WD (MODEL 3)" & ISUZU TX40 TYPE 97 TRUCK I.J.A.
WWII Japanese Military Vehicle & Truck
78 + 124 parts
Kurogane 4WD: New Tool - Not in 2008 catalog … Driver and machine gunner
figures are included.
Type 97 Truck: TX40 Truck parts of 09781 w/ the carrying bed parts … Driver and
mechanic figures are included.
I guess we'd better start hoping Tamiya will do the often rumored Type 97 Chi-ha medium tank....

Oh, by the way, note that the Isuzu TX40 truck is not the fuel truck included with the new 1/48 Ki-45 Nick, but the Army cargo model with a cargo bed replacing the fuel tank structure. Oh frabjous day.....

These kits are scheduled for a March 2008 release.
