A tweet from 3DOgaming alerted us to an article scanned from the first issue of the UK 3DO magazine (Winter 1994). It's a very nice preview of the then-upcoming port, with a special look at some of the updated ship graphics.
The rest of the magazine proved to be something of a Wing Commander bonanza, with a review of the other 3DO Wing Commander title, Super Wing Commander, and a very nice single sentence preview of Wing Commander III (then scheduled for January 1995).
Wing Commander also appears in two third-party ads, one promoting the entire 3DO lineup and one advertising the very magazine you're already reading. Look closely at the 3DO ad's Super Wing Commander screenshot: it's an alpha build that still includes the original Hornet VDU artwork as a placeholder.
