VentureBeat claims we're going to get a MET Remaster "Legendary Edition"

How? Shepard will be just as dead at the end of the remaster as they were in the original. 
You're comparing a trilogy to a single game, so of course there's more story. For individual games by themselves, I'd say MEA is the best of the four. 

Yes.
Followed by ME3 in second, ME1 in third, and ME2 being the worst.

It's really not that hard to make a write around. Canonized destroy ending with the high EMS ending. And nah, MEA is middle of the pack at best. ME2 as a standalone has the most replayability. ME3 has the best MP by far.

I don't understand why some people are so allergic to Andromeda as a setting.

It's an entirely new galaxy. The possibilities are utterly endless.

Even if you thought the game "sucked", you should still see how completely new stories (FAR more expansive than those in the OT) can be told.

Funny, my appraisal of the series has been exactly the opposite.

The setting, son. The setting.

No, it's not. MEA takes place in only one star cluster in the Andromeda galaxy, leaving 99.99999999999% of the galaxy just as fresh as if you uncanonized MEA. 

Has there been any other reliable sources confirming it exists though? Is he saying the Remaster itself it's fake or just the details are fake?

Depends on your definition of credible.  There have been plenty of places that are quoting reports that there is one being made, but I haven't seen one that I would put beyond still being a rumor that its being made.  I think the first report was from VentureBeat and one or two more places since they have made similar claims.

Here is the exact quote about it from VentureBeat that got everyone so excited.  I think another place has been quoted as "trusted insiders" as well, but basically I think it was the same thing.

Oh, and that HD remaster of an EA game is the Mass Effect Trilogy. Just don’t expect that to also launch on Switch — at least not at first.

I still have a hard time believing it, but there is always the chance for places like to try things to make money.  I just don't see a remaster of Mass Effect happening for to me it lacks the reasons to have one unlike games like Command and Conquer Remake.  The other thing that gives me pause from thinking this is nothing more then a rumor is that EA has a history of at least confirming the existence of projects after they have been reported upon.  A recent example would be Star Wars: Squadron where I get the impression they were planning on revealing it at EA Play because they just showed off the same trailer they revealed a few days before.
