I will start by saying this; this thread is NOT for flaming (as is any), and is meant for creative discussion. NO "this HAS to happen or blah-blah-blah"s should be said, and demands for the most-likely-already-completed HUD will be deemed as spam and will be reported as such. As a side-note, spoilers are present, and may not always be in spoiler tags. You have been forewarned.
On the said topic, this thread IS for analysis of what we’ve seen of the Halo 4 HUD. Comparisons to the Halo: Reach HUD are gladly accepted, and there’s also links below to popular references, with many more to come as they are cited in the thread.
Please note that what is discussed in this thread will not be deemed “Confirmed” until 343i themselves says that it is “Confirmed”. Any images will still be seen as the incomplete game until 343i says that such screenshots are from the final version. Basically, don’t get mad when someone says “not confirmed.” 
This will serve as a MasterPost. Links may be posted to images and/or videos regarding the Halo 4 HUD, and even Halo 4 gameplay as and when it arrives. Links will also be posted to such sites as NeoGAF. If Frankie decides to feed our starving bellies, that is.

Feel free to discuss the HUD to your hearts content. Make any reference you want to past games, and in general, have fun with this creative discussion.
Just as some conversation starters…
The score on the image provided seems…uh…off, if you ask me. Could there be a new version of scoring? Or have these teams been going at it for some time now? It claims that this is “BR Slayer”, and while this is a not-confirmed gametype, is it likely that we’ll be seeing this or something similar in MM?
From what we can also tell, Halo: Reach’s health system appears to have been scratched. Could this perhaps mean that Halo 3’s system is back? Or is health possibly incorporated into the shield bar? Or is this an entirely new system?
Finally, something I don’t know if many people noticed is the ammo for the BR, and the grenades. At first look, you can see the BR’s ammo clearly, with a typical 108 extra-ammo rounds, and, from what I can tell, a total of 66 usable shots per round, with 3-shot bursts. However, where are the grenades? I looked carefully, and saw THREE boxes in the top-right corner, all with "0"s in them. Grenade boxes, or something else?
Oh, and how about that Radar? from what we can see, the Enemy/Friendly Icons are more visible, but being able to see weapons/ammo crates has been rumored. Anyone care to provide input?
