Apparently they have recently acquired a prop from which small pieces will be used for prop cards. Artist Darla Ecklund who did sketch cards for series 1 has been removed as an artist for series 2.

Word on the sketch artist message boards were the release date would be March 31st. As of this writing I do not know if the new prop cards will affect the release date.
