You realize that you need some kind of os for managing and installing an update? Yes? Oh... eh. No.

It has an obsolete os, like we all knew before, as it has all the drm-stuff.

No MS confirmed it has no DRM even in the box, the OS is just not a complete one. 

Isn't AC normally running at 30FPS? I mean there's tons of frame rate drops on AC3 on consoles.

I would be concerned if AC4 can't even run 1080P at 30FPS on the Xbone.

On the one hand, considering it's a handsome game even on Xbox 360 and PS3, it should still look great on Xbone even if it's only 720p/900p.

On the other hand, considering even the PS4 version isn't leaps and bounds ahead of the current gen versions graphically, if Xbone still can't handle it at 1080p, that doesn't bode well.

We will never really know as it is mandatory but I believe they "locked" the old firmware with the screen for mandatory update so people don't get to see the old firmware. And eh... Where did they say that?

For sure this has nothing to do with requiring a connection. There is no “DRM removal” in the Day One update because none of the consoles were ever built with that stuff in it.

Oh this was a totally different message than we got short after the 180.

This is worrying, since AC targets 30fps, and does not even use a next-gen engine.

Yeah which one to beleive or are they just saying what ever they like to quell rumours.
