British subs?

Don't get me wrong, I admire the british navy in ww2 more than the american one, but by gameplay standards, a british sub campaign would lack the punch. What's the fun in a sub game if you're not up against a big fleet? The british, americans and japanese had imense fleets, and they were used very efficiently and ruthlessly, that's why it's so fun and scary to play against all of them. The first months of the PT with the americans are almost as apocalyptic as the late years of the AT. An american expansion (or new game) is clearly the way to go but this time I'd love to test my skills as a japanese too (even just one class of sub, not midget or airplane hangar).

I'm already scared.
