I've seen ads for a DP32SD at Musician's Friend, it looks like the DP32 but the photos do show "SD" on the front panel. The MIDI ports are gone It is not on the Tascam website yet.
Current street price is $550. DP32 is still selling for $600 (DP24 for $500) but my guess is they are about to be discontinued.
The DP24 and DP32 are the last consumer digital multitrackers still available that support MIDI.
