I think it is fairly evident from the words underlined below that the MOS software/process has been improved to enhance the battery life.  

As this point we don't know if other companies, and the products which may have application for this new feature, will want to incorporate this function into their production. It may require a substantial change in the systems design and production of the products in question and may not be cost effective from their perspective.

Don't forget, we have no indication that our MOS is in use by anyone outside of e.digital. This new technology may not be enough of an incentive for any product modification.
