N7 Day brought us plenty of Mass Effect: Andromeda news yesterday, but it looks like the Amazon store page has brought us even more!
If you go to the store page and look at the image on the Xbox One's Digital Code listing for the game, you'll see that it explicitly states the game will be playable on March 21st, 2016. The '2016' could simply be a typo because the March 21st date for 2017 was listed before on Amazon.
The interesting part is that this release date was listed before on Amazon! The store page for the game's art book said that the book would release "simultaneously with the game” and the book was dated to release on March 21st, 2017.
BioWare has already stated that the game could see a delay if it isn't meeting their standard, but it looks like as of now, the game should be releasing on Tuesday, March 21st.
