Big thank you for the updates. 
Am I the only one that groans when she reads that?
More freedom translates in my head to a less linear game, with a weaker story, and way too many zones to explore that will overwhelm the actual plot.
I love DAI, but please please don't let ME:A catch InquisitionZoneAThon-itis. 
I also thought DA:I was not exactly great with it's open world as it was implemented. However, I am hopeful and optimistic that "more freedom" will really be an enrichment for Mass Effect (at least for me personally) for a number of reasons:
1. In the beginning, Mass Effect was very much about exploration. Sure, the worlds in ME1 were empty and the MAKO's handling was weird but the concept was there and it was only taken out in ME2. I think in principle, the exploration part lends itself very well to a scifi space-traveling game and it only needs to be executed well and I did feel like we lost something there in ME2/3 when a shuttle always brought us right to the 50 square feet that mattered.
2. DA:I was BW's first attempt at building fairly open and large terrains with a large exploration aspect. A lot of the downsides in DA:I were clearly due to a lack of experience in this area. Even though the teams are different, I do hope that there will be a lot of exchange of ideas, consulting and feedback between them, so that the ME team can steer around some of those pitfalls and overall improve the feel and the pacing of the game.
3. Part of the last point is to develop a plot that lends itself well to the exploration aspect. I hope the ME writing team will have taken this into consideration as the exploration aspect seems to have been their very early core concept for Andromeda.
4. This may not apply to everyone but for me personally, the combat mechanics of ME and the general gameplay (with the TPS + powers system at its core) are much more enjoyable for long term repetition than DA's slow and (to me at least) very repetitive combat. I know there are those who disagree but I can easily spend hours running around, trying to find good cover spots and try and be precise with my shots without issue, while in DA, I feel that once I found the right skill combination for my character class, I don't have much else to do than to just press the right button combination over and over. Since ME's system feels much more dynamic and varied to me, I don't think I'll mind spending more time with it between story snippets then I did in DA:I (but as I said, that may be just me).
All in all, I am really looking forward to ME:A's more open approach and I am quite optimistic that it will surpass DA:I in it. Of course, there are still many pitfalls that BW has to steer around but all we can do before the game is out is wait and see if they'll manage. The approach itself is a good one in my mind.
@OP: Thanks for letting us know. Looking forward to 6/12.
