And I take it that Holographic thing-a-ma-bob is for the stereoscopic 3D and not some new tech.
Two interesting passages from Wikipedia on the topic "Holographic Data storage":
The three main companies involved in developing holographic memory, as of 2002, were InPhase and Polaroid spinoff Aprilis in the United States, and Optware in Japan.[5] Although holographic memory has been discussed since the 1960s,[6] and has been touted for near-term commercial application at least since 2001,[7] it has yet to convince critics that it can find a viable market.[8] As of 2002, planned holographic products did not aim to compete head to head with hard drives, but instead to find a market niche based on virtues such as speed of access.
and,
Some have speculated that Nintendo will be the first video game console maker to implement holographic data storage due to the uncovering of a Joint Research Agreement between InPhase and Nintendo.[12]
Nintendo is also mentioned in the patent as a joint applicant: "... disclosure is herein made that the claimed invention was made pursuant to a Joint Research Agreement as defined in 35 U.S.C. 103 (c)(3), that was in effect on or before the date the claimed invention was made, and as a result of activities undertaken within the scope of the Joint Research Agreement, by or on the behalf of Nintendo Co., and InPhase Technologies, Inc."
