Well, that's in a sense what they're going to do. Message Walls as we know them now are going away, but the post I linked to would seem to indicate they'll be replaced with something similar.

As for article comments? I don't know, as they are now they're not compatible with the new format we're switching to, so they have to go away. It's really not a major change though.
