The nail was put in that coffin a long time ago. It was asked for, debated and denied. They said they prefer to look to the future.
You really haven't played it in 7 years? I replayed the series while waiting for MEA.
I don't own a 360 anymore, and went all digital years ago. The only way I know of to download ME2 and ME3 on Xbox One is subscribing to EA Access, which I refuse to do.
You can't actually. They're not available. Not every game was made available for download in those days, and EA only made them available through EA Access when they were made BC.
