I think the US Title (and the IC Title to a lesser extent) are in a state of flux while they decide what to do with the WHC. If they continue the title unification between the WWE and WHC (which will mean the WHC fading into oblivion), then the US Title will regain some prestige and become more visible. If they split them again, then the US Title will continue as it has been, mainly being irrelevant (I mean, they had a recent title defense on NXT if I'm recalling correctly...I'm not even sure if it was televised).
The other option would be to re-split the main event titles and build a new brand split (this apparently has been talked about, although I don't know how seriously) and have the US Title again be treated as on a par with the IC Title, but on the opposite brand from the IC.
