As someone mentioned recently on the Me 110G thread, it is very unlikely that Tamiya will ever pop out a series of late metal winged Corsairs. I have the old French resin conversion for the Trumpeter kit, but it is pretty much rubbish, with a 5mm difference between cowl and forward fuselage for example. From basic parts and a few differences all three late versions can be modelled, and there are plenty of users, US Navy and Marines, France, Argentina, Honduras etc. With a bit more work an F4U-4 version can be turned out.
I reckon it would outsell the Me 110 G, I'll be in for a few myself.
