What would you want to see in plarail?

I'd like to see some british outline steamers, I'm sure they would go down a hit with the japanese market as well as worldwide if available. Things like the A3 (aka Flying Scotsman), A4 (Mallard), Coronation Class, the list is endless and could easily use the existing chassis and in some cases they almost have the bodies as well, after all Gordon is all but an A3, Spencer is an A4, I'm sure they could easily replicate the others as well...
