The latest album exploded the first week (helped somewhat by heavy discounting) but it didn't have the legs of the previous one. It sold respectably, but I'm certain that they were hoping for better.
The real question is "now what?" When shock is your schtick, how do you keep the audience shocked ,and thus entertained? You can keep pushing outwards, but when you start in the meat-dresses and wtf video realm, people may already be expecting the outlandish. You can try zagging instead of zigging - a country album? Opera? Gaga unplugged? - but there's less guarantee that her fans will follow. It'll be interesting seeing the next move.
