I think it may be time to prod the model companies again, and it seems this forum may actually work at doing so! Perhaps it was just coincidence, but the results from the last time around were a USS San Francisco, HMS Repulse, IJN Kongo, and now I hear a 1/350 IJN Akagi is now in the works too! So let me kick this off with my suggestions, and please feel free to chime in with yours! Remember, 1/350 scale!
German CA 'Prinz Eugen'
Japanese CL 'Yahagi'
CL USS Brooklyn
BB USS New Mexico (modernized)
CA USS Northampton
Japanese CA 'Mogami' (with converted flight deck aft)
Japanese carrier 'Ryujo'
Italian BB 'Littorio'
French BC 'Strasbourg'
BB HMS Warspite
And if they REALLY want to get bold, here are a few WW1 kits that would be very welcome!!
BC HMS Lion
German BC 'Derfflinger'
BB HMS Queen Elizabeth
German AC 'Scharnhorst'
And finally, my two FAVORITE pre-dreadnoughts,
AC USS Brooklyn
Russian BB 'Oslyabia'
