Given that 'setting support' is now a dirty word to WotC
I don't think this is true. I do know that WotC fully intends to support its settings beyond the core 3 products by publishing online content thru DDI. Whether or not this works or is sufficient to count as support may be up to the individual, but I do credit them for trying.
Also, I think if WotC had a proportionate amount of success with DL as MWP/SP did with it, in terms of distribution reach and branding penetration, they'd be happy enough.
Cheers,
