Two of them today. The first is from Avault talking about Homeworld. It's a light mention, they refer to Wing Commander and Star Wars as the "great ones" in space combat simulation. You can find the article here. Thanks to Shades.
I'd like to add that you will also have access to a data terminal that will display messages from characters, briefings, debriefings, ISN reports, and which will give access to the official EA database, among other things. Boning up on alien races and historical events could well help with how well you do in missions. You will also be allowed to go hop in your fighter in-between missions so that you can mess around with flying until you're called for a mission. As far as character interaction goes, there is some, but not in the Wing Commander way that you're thinking about. This is a combat sim, not an adventure game or RPG.
