Kotaku - Sources: Mass Effect: Andromeda Will Not Get Single-Player DLC

You can't just look at initial sales though, because a lot of those were preorders from people hyped about the series coming back.  If the sales fell off drastically after that then that would give EA pause in pushing out more content.

I'm sure they're tracking things like, what percentage of players finished the game, how many played it multiple times, when was the last time it was played.  If those numbers don't look good, they would also have to think about future content as well.

Andromeda was never going to be a financial failure just due to players buying the game on the Mass Effect name, the success of the OT.  However, from here on out, Andromeda is living on its own name, and not the OT anymore.  So whatever they release now they will be taking a risk.

I'm kind of shocked by the news of no DLC, I thought they would probably have already been working on something even before the game came out.
