Most likely the Shield get spun into feuds with the peripheral babyfaces - Big Show, Miz, Ziggler, and Cody - in some combination. But they're the enforcers for the COO and that's going to keep them in show-ending segments (with THE biggest active babyface in the company, incidentally) for the foreseeable future, and is a much more prestigious position than feuding with the Usos or Prime Time Players over the tag titles. Sooner or later there will be a ShowMiz reunion or Z-Rhodes or some other horribly-named combination of the above will challenge for the tag titles, and Cody or Miz will challenge for the US title.
The angle's less than a month old. You gotta give it some time. If they're still doing the same thing a month from now, that's the time to bitch.
