I am tremendously excited to see what the ME team can do with Frostbite and next-gen systems. The DAI trailer looked incredible, and I think sci-fi environments (uncherted planets pls) can look just as spectacular as fantasy ones.
Particularly if MENext is next-gen only.
I have a pretty strong suspicion it will be. This game won't be out for a long, long time. When it is out, only some particularly ardent Japanese developers (and Western sports franchises of course) will be supporting the PS360 in any noteworthy fashion. I'm almost expecting Metal Gear Solid V, which won't be out until at least a year from now if not closer to two, to announce a drop of legacy support before the end.
And really, I would be delighted to see Next on PS4/XB1 only. And like you I am salivating at the thought of ME1 skyboxes of that caliber. I never missed those Uncharted vibes as much as some others when it came to ME2 and ME3, but one look at the recent trailer for Inquisition and my heart skipped a beat and my brain immediately went to November 2007's glorious red planets.
