I guess there was a review embargo, and it just ended today. There are TONS of gameplay videos and reviews popping up along with the beta announcement for April 23rd.
The running looks like much of the same (in a good way), and the new combat looks amazing. There is a new runner vision which has, thankfully, been confirmed to be able to turn off. There is a runners vision like in the videos where it directs you where to go, one like how it was in ME1 where things you can use are highlighted in red, or completely off.
