Thats good, should be a SSD though, screw HDD's.
I put this in the other specs thread but thought I'd post it here since it's being discussed.
I'd prefer to see:
1. 16Gb memory in this HD age & future-proofing
2. SSD over large HDD for performance
3. Potential dual network ports using an aggregate system, stream or download a movie while playing an online game, provide bridging systems for other entertainment devices or mobiles/tablets or also provide an aggregate stream system as many ISP's support this. You could even use one port for streaming or one for hosting or both for gameplay etc.
4. Multiple screen support so coop on the same console could be done without splitscreen. So many players own multiple screen these days why not suppot two or more monitors to handle two players each with their own controller and screen? Or be able to up the game resolution and split a single player game across 2/3/4 monitors?
5. Streaming built in e.g. YouTube rendering from any game, voice/screen streaming for live game streaming to Twitch or a new XBL service etc.
That's just some ideas but so far the rumours are looking really tame in terms of deliverable features. I hope they get creative and more is released away from these specifications only rumours.
I'm also hoping for vastly improved AI, physics, interactive elements, procedural mechanics and more. If developers use the new resources just for graphics then it's fail big time. We need more developer resources spent on key game elements like AI, physics etc. Game worlds that are always on developing, interacting and generally using the hardware resources for more intelligent features than just larger redraw distances and higher Levels of Details (LOD) systems.
