Mass Effect 2 GDC Observations

MTV Multiplayer brings in some observations of the changes made to Mass Effect 2 compared to the first, based on a glimpse from the Game Developers Conference. Sparse info, but of interest if you've been following the game.
Here's what little I picked up: In the combat scene, the circular targeting reticule of the first (Mass Effect) appeared to be switched to crosshairs that expanded and contracted during combat, possibly due to the rapid firing of the character's rapid-fire gun. The dialogue scene appeared to use the same mechanics as seen in the original game. It showed lots of cars flying through a city. The main character, a blonde man, was speaking with a blue alien woman. (See? Not much I can conclude from that!)
