Sigh, no it doesn't. The first part is just asking what everyone is asking. How will the Milky Way rebuild?! and Shepard being mentioned is because plenty of folks do also ask what Shepard will be up to if they are alive.

Wasn't it already confirmed (by this image and other posts on last N7 Day) that there was a good chance ME would continue in some form?

^erm yes, and this poster is one of those pictures from that announcement

They took down a caption but the most important part is that say the Shepard and the survivor are left to pick pieces. which could mean Shepard is in the next mass effect
