Latest word we have from Anthem is that new D2v and AVM 50v orders are currently taking about 45 to 60 days to ship from when Anthem receives the order (i.e., when the dealer and his regional distributor actually place the order with Anthem: The day you buy at your dealer may not be the day Anthem actually receives the order). First come first served, except for warranty replacements which go to the head of the line. I don't believe any dealers have managed to keep either of these units in inventory. This is not very different from when the original D2 launched in 2006.
Due to the press of new unit orders, Anthem now says it doesn't expect D2 -> D2v upgrades or AVM 50 -> AMV 50v upgrades to be orderable until June. Final pricing on such upgrades also has still not been set.
Both the unit firmware for the D2v and AVM 50v and the software for Anthem Room Correction (ARC: For all ARC-capable Anthem processors, not just the D2v and AVM 50v) have just had significant updates released -- downloadable from Anthem's web site.
As always, discussion is taking place in the massive "tweaking" thread:

Interested folks should read the first post of that thread and then start scanning backwards from the end.
