Well seeing as how the wishes of the 1/35th scale crowd is well represented here, I think I shall speak up for the Braille Scalers.
The top Armor models that I in particular want to see in 1/72 scale are:
M-26 Pershing
T-72 tank with decal and parts options for Middle East Armor.
M-109 Paladin S.P. Gun
Russian T-90
More modern French and Italian Armor such as APC's, and Scout vehicles.
Mobile AA systems from all countries.
HEMTT trucks, all variants.
MLRS from US and Germany.
Dragon Wagons
I think that covers it quite well so far. I think there is enough good representation of WWII German Armor to keep us busy for awhile, but the kits I just listed are the most neglected subjects in the Industry.
That's my
