If so by your best estimate:
- How MUCH of the 8GB would be actually available for game development?
- Like the PS3, are we likely to see reduction in OS footprint (even with the addition of new features) over the years?
- Is there a chance the OS will have different footprints depending upon when a game is being played and otherwise, akin to Vita?
Sleep/resume and instant play take zero to minimal RAM, and background downloading has extremely minimal requirements even if it isn't handled by the coprocessor they mentioned. I didn't see much yesterday that would bump OS requirements up from rumors assuming the rumors took the sharing aspects into account.
On the other hand, I'm not sure why they wouldn't implement Vita-style swapping, even just as a "just in case" measure. It's extremely similar to the sleep/resume function technically, isn't it?

No, background video recording will be stored in RAM.
Yes and no? It's probably piped directly to the built-in H.264 encoder rather than writing raw video, so at 1080p/60 it -might- be eating a few megabytes/second of write, all of which is easily preemptable. Meaning an output buffer of perhaps 64MB is more than enough.
