Panasonic announced a single-card reader for their P2 cards.  $350.  Two USB connections, one for Power and the other for data.  Due out in April.

Panasonic Broadcast has introduced a single-slot P2 solid-state memory card drive, the AJ-PCD2. Joining the company’s growing line of P2 workflow tools, the PCD2, with two USB 2.0 cables supplied, requires no separate power supply for file transfers and offers total compatibility with Mac and Windows desktop and laptop computers.

In contrast to other single-slot offerings, the PCD2 will afford complete flexibility and reliability in addition to being a low-cost solution.”
