According to Pachter, the PS4 and Xbox 720 will have 2 TB hard drives. That pretty much means users can download anything they want and never get rid of anything and will have room for a couple of hundred games.
Previous rumors have suggested that the new consoles from both Sony and Microsoft will launch with fully developed and integrated digital distribution models, which would allow players to get all the content they are interested in without ever going into retail store.
Other rumors about the PlayStation 4 and the Xbox 720 suggest that they will include upgraded motion tracking systems, better support for 3D and more processing power.
A source inside Microsoft also claims that its next-generation device will be launched in time for Thanksgiving 2013.
