Pioneer Japan finally announced their new DVD Multi drive.
I'm guessing this is the main difference between the A10 and A11:
(1) Newly designed Disc-Resonance Stabilizer to further improve the accuracy in high-speed read and write operation
The Pioneer new drives' Disc-Resonance Stabilizer - the projections arranged on the inner surface of the upper case - controls the airflow generated by disc rotation to minimize disc warp which can be caused by disc resonance during high-speed rotation. The new disc tray with airflow adjustment holes also helps suppress disc resonance. As a result of such structural improvements, the new drives provide users higher accuracy and stability in read and write with quiet operation even in high-speed modes.
Let's just hope the media compatibility is better than the 110/A10 series.
