He talked about upcoming DLNA support for PS4, a redesign for the PS Mobile App and PS3 entitlements possibly carrying over to PS Now.
In regards to much awaited DLNA support, IWorkForSony estimated an early 2015 release date. He also noted that Video and MP3 support could come as early by the Holiday season this year.
I’d say early 2015 for DLNA.
MP3 and Video Players by the Holiday season (MP3 maybe sooner)
A much need redesign to the PS Mobile App is also in the works, which IWorkForSony described as more functional and modern.
