Samsung recently received Wi-Fi certification for their BD-C7500 Blu Ray player.  Filings for the BD-C7500 describe interesting media extender and media server features.

Currently, Samsung’s Blu-Ray players support Netflix and Pandora streaming, as well as media streaming from a PC.  But the description of ‘media server’ features suggest that the BD-C7500 may include an internal hard drive that will allow users to store media on the player itself.

At this point this is purely speculation, but the BD-C7500 is definitely a Blu-Ray player to keep an eye on.
