Well, if true, it sounds...pretty good. Though by mentioning the "final events" of ME 3, then it called a sequel, of sorts. Takes place after ME3, how long after, who knows. But the setting is so far removed from the last series, nothing that happened there, can affect what happens in an entire new GALAXY. Works for me I guess, it's a brand new story of discovery and adventure, unshackled by the endings of ME3. I really hope it won't turn out to be BS, I like where this is going.
However...I doubt Bioware would put THIS MUCH info on the next Mass Effect game, which has barely any info about it officially, into a survey. And if they did, wouldn't they have a NDA thing to sign or whatever? I mean it all sounds pretty good, but it's fishy.
