The MDR-1A has just became available for pre-order on Sony USA's website for $299.99 with a 9-30-14 release date.
I'm really hoping that these will have a significant SQ improvement over the 1R/1R MkII since the 1A's are using a new ALCP 40mm driver.
Can't wait to hear these for myself!

9-5-16 Update:
2 years after the release of the MDR-1A, Sony has just added another version of the MDR-1A to their lineup!
The MDR-1A Limited Edition has a matte black finish with perforated leather earcups and headband. It should have the same MSRP as the regular 1A.
It sure looks sexy!
