The PRS-300 is the lower end of the two models with a 5-inch display, 440MB internal storage but no expandable memory card slot.

Both models will be available in red, black and silver, but that is all the info the service manuals are giving up. We'll be keeping our ear to the ground for the latest on this, so keep it locked to for the news as we get it.
