Hi Bill,
This is just a guess. But I think that if sales of the 200th Arizona go well, then Trumpeter may opt for a whole range of 200th scale battleships. They did release a 350th Nimitz and a 350th Yorktown so they have plenty of experience releasing plastic ship models of around 3 foot in length.
I'm hoping they go one stage further and go for a 1/32nd scale Lancaster...but I think I'm dreaming too much!
Cheers,
Dougie
