Gaga Rock in Rio 2016 performance means new album before then

I expect it will come in May most likely, when she'll be able to get the best network TV promo, and safely slotted in between Katy's holiday album and 4th studio album.
The last hurrah. The last era where she will get the budget of a big pop star unless she turns the tide of her career. Her last chance. It will be interesting to witness.
