Honestly, to me it's pretty obvious.
There's *zero* way anybody can just turn an Xbox One into a full-fledged debug kit will full access to the hardware. Just as in there's no way indies will have full access to the hardware unless they push their games through the Live marketplace or whatever the hell it's going to be called on the Xbox One (and not through the Windows 8 Store, which is what this is most likely referring to). You know why? Because if they did, you'd have a way to do a lot of nasty stuff with the console that Microsoft truly doesn't want. This essentially means the console is an open platform where anybody can just develop anything they want, and that's the opposite of the direction MS is taking.
So all this information can mean a few things.
1- If you want to self-publish on the Xbox One, you *absolutely* must do so through the Windows 8 Store (if you're an indie, that is). That implies the restrictions (not limits) that apply to Metro apps (access to less ram on the Xbox One because the Windows 8 portion of the console reserves 3 gigs of ram for itself).
2- If you want full access to the Xbox One hardware, you *absolutely* need a publisher to push content to the Xbox One Marketplace (the XBLA equivalent, again I have no clue how this is gonna be called now). This comes with zero actual restrictions towards the console (you can push it to its limits!) but it need to go through Microsoft QA and carries the inherent problems of XBLA publishing.
Now what I'm wondering is how much ram is actually reserved for Windows 8 on the Xbox One. Do we have a clear confirmation as to that? Because should the Windows 8 portion of the console be able to reserve all the available ram in the console, it could, in theory, have as much ram as the console will allow, but still be restricted to Windows 8 Apps and not have full access to the console.
"No indie ram/access limit" can mean a shitload of things. It can mean that indies can self-publish games on the Xbox One's Live Marketplace with full access to the system. It can mean that there's no limit imposed on indies while developing for Windows 8 on the Xbox One. It can mean indies can develop using an Xbox One as a dev kit and push to the marketplace (not the Windows 8 Marketplace but the Xbox One marketplace). It's so vague and ridiculous.. Microsoft just is unable to clearly state their intent for *anything*.
BTW, Unity has added in support for Windows 8 with Unity 4.2 that released this week. We work extensively with Unity at my job and we found it kinda cute we could now push Windows 8 and Windows Phone apps, but lo and behold, you can only build Windows 8 Apps and Windows Phone apps if you're running Windows 8. The API and the SDK aren't available to Windows under 8. I understand from a debugging standpoint - if you don't have Metro, how could you even run a Metro app, but it's kinda sad you can't do anything without it. So my guess is they're going to push hard for indies to switch to Windows 8 to be able to publish anything on the Xbox One because it'll be required, and they're probably thinking that PR-wise, if even hipster indie developers are using Windows 8, why aren't you?
