Sorry, late to the discussion hear.
I'll be honest, my gut says "no." And the primary reason is simply that I don't think Keith Baker is making plenty of Eberron content on his own.
It just feels like a revisit that doesn't need to happen, as KB Presents is quite happy to keep publishing Eberron content from the mind of it's creator. I feel like the D&D Team likes to create content they haven't done before, or stretches boundaries in some way, and an Eberron revisit seems antithetical to that approach.
That said, I haven't thought about the "setting revisit" in a long time so don't know who is the best target. Probably FR, to my chagrin.
