it has been spotted at namm, but as of now nothing came up.. description sounds interesting.
there´s been one confusion though - it´s not a tap tempo delay (I´ve yet to see a bbd delay with actual tap tempo), but a multi tap delay:
"The AD999 Pro features a new “Multi-Head” mode that is operated via three top-mounted mini switches. In Multi-Head Mode, midstream delay signals (which are taken from the middle of the BBD delay circuit) are added to the normal delay signal to emulate the sound of Tape Echo multi-head operation. These feedback loops can then be selected by the user in a variety of combinations to create complex multi-tap delay repeats and rhythmic delay effects such as triplet- and sixteenth-note rhythms against the main delay repeat. The Multi-Head mode can also create a striking Tape Echo simulation, or it can be used to create ambient effects such as large room and concert hall reverberation."
You can get it to oscillate like crazy, which I find cool, and it does its job very well.
