The new DBP-2011UDCI is reported to use the new ABT 2015 VP chip, which is the latest iteration of the ABT 2010. It's a pin-for-pin replacement for the 2010 with a few refinements that should help image quality even on BD discs.
Expect to see other hardware makers moving to the ABT 2015 also.
Interesting that Denon has suddenly come out with 2 similar models and pricing to the 2 current Oppo players. But don't expect Oppo is sit silently by and ignore it.
