I think the basis of that PS4/X1-only thing is the Amazon listing for "Mass Effect" on PS4 and X1 that popped up several months ago. Perhaps there's more to it than that, but IMO, if that was legit by any definition, it was in reference to the looming announcement of a Trilogy next-gen release, as I'm fairly confident that thing is coming out first. And I'm fairly confident it's coming because I still don't believe someone like Aaryn Flynn would have taken to NeoGAF and asked what they'd like to see in a "theoretical" release except to generate buzz without actually confirming it.
Regardless, though, since NME is likely a 2016 release, I'm very doubtful there will be PS3/360 versions. Sorry, Stealth. That just seems like an excessively long time to still be making previous-gen ports even by this generation's rule-changing definition. :\ On the flip side, it'll mean going "all in" with the PC, PS4 and X1 versions, meaning not having to scale anything based upon what might not be possible with the PS3 and 360 hardware. Maybe there'll be a hot sale on an X1 (or PS4, or gaming PC) that'll pull you into a purchase just in the nick of time, Stealth.
That does seem like a distinct possibility.
I and Vertigo (Teddy) had a bit of a discussion, and we concluded that unless they make any reveal in early March (PAX, GDC), then a 2015 release is probably unrealistic.
If they go for a 2016 release, then I guess that the official reveal will probably be in next year's E3 (June).
Yep. PAX or GDC is possible. Quite possible. I'm still conservatively counting down to E3 just in case... regardless, E3 will likely make the biggest splash presentation-wise out of all three venues, of course, so it'll be something to behold no matter where NME is formally unveiled. And of course the rush of articles that'll follow will give us a nice taste of what to expect.
Seems like it's going to be that way. I'm just surprised that a game like ME Next will have more development time than DAI, which supposedly had to deal with engine transitions and building new systems from scratch.
And judging by what the Dragon Age team accomplished with DAI in terms of scope, with extra dev time, ME Next looks like it'll have the potential to a really big game. Just hope they get the design choices/timeline/atmosphere right so that we have an authentic Mass Effect experience 
DAI's transitions were nothing to scoff at, of course. It had a lot to deal with, including how best to tackle the elephant in the room that was DA2's relatively negative legacy in the eyes of the gaming public. But I've always held that NME's transition has been equally daunting; whereas David Gaider and all his Edmonton allies have gradually been moving through broad, overarching narrative ideas they envisioned many years ago, NME has largely switched studio locations and shuffled some of the franchise's key positions in the wake of the end of the original vision for Mass Effect's ultimate destination.
ME3 capped off everything that Casey Hudson, Drew Karpyshyn, and, yes, plenty of the folks still around to work on this next project, came together to create all the way back in 2004-2005. Doubtless there were all manner of things which did not develop/conclude as intended, since it was, like Gaider's vision, broad strokes the whole way through, but the point is, the painting was completed. It was "back to the drawing board" for an appreciable amount of time, what with Montreal now helming, what with Chris Schlerf now lead-writing, what with the first non-Shepard experience, and then what with the new engine, entirely new ME-centric assets to build, so forth. It might not sound like terribly much, but then, this is why the first Mass Effect had the longest development time in the trilogy. It's not that it had so much more content than its sequels (although "content" can be a very subjective concept, heh) so much as just how much "boldly going" was involved.
Plus, yeah, it's gonna be a big game in terms of play space, and it's going to follow Inquisition's lead by ensuring that its regions (worlds!) are colorful and diverse in addition to vast. And above all else, as BioWare stated in its press release on key personnel for the project, this is the first time in the series since the original game that it's focused on innovating a great deal. So that means new gameplay systems the likes of which we've yet to see in a sequel. And that means time spent creating them.
Just realised... MENext will come out after SW: Force Awakens hits TPB... um, I mean cinemas...
Damn... still it's so much waiting...
I just want my damn MENext annoucement, so I can finally pre-order the overpriced uber nerdy Collector's Edition and be calm that I will get my game before all pieces are sold.
The Force Awakens is going to do good things for space opera, so long as it is well-received of course. It's going to help Star Trek, Stargate, Mass Effect... space is big when Star Wars is big, and there's going to be a new generation of miniature Jedi eager to see what this space thing is about, and I think some of them are going to be captivated by the adventures of not-Shepard as a result.
