This is just like HD-DVD.
PLDS (Pioneer & Lite-On Digital Solutions) has announced that they will release a portable Blu-ray drive, the DX-401S. This BD-ROM drive will connect to any PC via a USB 2.0 cable enabling users to watch any Blu-ray movie on their computer without installing a Blu-ray drive. No price has been given at this time for the device, which is expected to be released sometime in April.
