GameSpy.PC has an article on StarCraft 2 which compares the game's new interactive gameflow portion to that used in Wing Commander. Oddly enough, this isn't the first time such a similarity has been noted - people seem to notice sparks of WC in the strangest places:
The Mara Sara bar is the first example of what Pardo calls a "between-mission space." While not an original concept (the Wing Commander games pioneered this idea years ago), the beauty of the game's artwork shows both how far the technology of computer graphics has come since those days and the oft-lauded talent of Blizzard's art department. Each of these spaces is loaded with stuff to click on and interact with. Results range from full-blown cut-scenes that detail elements of characters to small things like a jukebox in the bar playing music, a television showing news reports about what's going on in the galaxy, and even a window on the bridge of Raynor's flagship giving a nice view of whatever planet his ship is currently orbiting.
