Thought the thread could use a refresher on the video. Took me a while to find it. 
Anyway, looks great to me so far. The first thing I noticed is the emphasis on "new worlds" and the realism of the suit designs so far, which are two things I really want to see. Also, ME on next gen is gonna be pretty..^^
I'm not really down with the whole ark to a new trilogy idea. I want to see them building a new civilization on what's left of the old, new players in power struggles over what the new paradigm is going to be, just a few decades out. A power vacuum scenario is interesting. I hope we're not necessarily playing another marine this time, and hopefully we'll get species selection. I want to maintain some ties to the old trilogy, a few recurring characters to let us see how things have changed and are evolving (storywise). That last ending choice was bad anyway, too broad, so I have no loyalty to it. I prefer they replace that citadel sequence completely, everything after the elevator. They could respect it as a mental interpretation of what Shepard went through without preserving the results. A wave of some kind still happened, just not canonizing the destroy/control/synthesis/reject chain. So we can build on the existing franchise rather than shunting it off to the closet of memory. I think incorporating the idea of the ark in other ways makes sense, though.
