They'll demo the combat for sure. BUT, if BioWare wants to keep to the premise of showing off "your Shepard" (purposefully excluding plot elements or characters that could differ from any player's choice in-game), they will include James Vega since your actions in previous games most likely could not have affected his existence. Also, they might include the "red shirt" of the game as the second squadmate. You know, the character who dies in the first mission like in the first two games.

I never pursued a relationship in the first Mass Effect game, the only interesting character of the three choices was Kaiden and I have never really gotten around to playing as a female Shepard. But is BioWare really not going to reward those who decided to only have a relationship in the second game?
