You're forgetting II for WSC, IV for SFC/SNES, IV Easytype for SFC, IV for WSC, V for SFC, VI for SFC/SNES, XI for PS2, and the billion and one special/international editions of things. Yes, I'm aware these are the Japanese releases, but I figured since J3cht threw in FF for WSC I might as well. There is also the planned release of FFI for cell-phone (never to be released in the US of course).
