Shot97 has uncovered a fantastic preview of early '90s Origin plans. It dates back to the April 1991 issue of The One in the UK. This puts it very early in the development of Wing Commander 2, and as such, a lot changes between this point and release. You can see right at the head of the article is the Confederation corvette design which actually the Sabre model! It's painted up in green capship colors prior to being deemed a fighter (a similar process occurred with the Crossbow). They also talk about a mid 1991 release for WC2 and 1992 for WC3, which were a ways off from that. Speaking of delays, Strike Commander is also heavily mentioned, but it's called Ground Commander at this point. There's also mention of ports for the Genesis are arcades, whew!
