Kotaku recently reported on a massive leak of Sega documents from the 1990s. One interesting bit for me: Sega's release calendar lists a Saturn port of Wing Commander IV for October '96. I don't believe that was ever announced (or otherwise leaked).
A Saturn port of Wing Commander III, not mentioned here, WAS announced and was supposedly shown in some capacity at the first E3 in 1995. Little else is known!
The leaked documents also have Sega's internal estimated release dates for the Playstation ports of WC3 and 4. They're just a month off for 3 (February vs. March '96) but way off for 4 (September '96 vs May '97). It's unlikely that a Saturn port could've shipped in October '96!
