Some of the things that I notice.
-The First Kill on that Magrider seemed very quick.Not sure if it was a bunch of reavers spamming it or not.
-Night time looks perfect.
-Took longer to kill other Magriders
-It looks like the Killcam shows where you are.
-The effects on explosions look really great.
-Don't know if they are still hiding the UI or not.It was lacking when Matt was Infantry
-Doesn't appear to be a start up time for entering vehicles.
-The map is just a solid blue no more colors really.(Just a demo still though it can be changed hopefully)
-Appears to be Rocks in the Biolab?
-Nice demonstration of hover left and right and of the afterburners.
EDIT
id not watch part 2 yet.
