With Gaga's silence, i can only speculate the drama thats behind the scenes. Like maybe she's gone for plastic surgery (doubt it but who knows)
or she's having dance classes , or she's re-shooting the DWYW video due to the R.Kelly saga(by removing the nasty,raunchy Gaga and bringing cute Gaga having fun with R.Kelly) or maybe she's recording a new album for 2014 (like the Fame Monster) to release through the App. or just having a breakdown and no longer cares about the FAME, maybe even getting her wadrobe,image and dancing together to bring Gaga like never before , so that she can save the sinking ship that is ARTPOP, or maybe she's making videos for the whole of ARTPOP and bring the era to an epic close with out of this world creative videos(i dont care if it has been done by anyone before but Gaga's videos are unique and eccentric, having lots of them at once would help in artistically interprating Artpop, in addition it would be a massive surprise for the G.p and she'll be talked about everywhere.
or
All hope is not lost. Stay positive
