This is what needs to happen. After the tour, she stops doing stuff. She doesn't have to promote You Da One in my eyes and We Found Love almost definitely will overshadow her on the charts no matter what; it's chances at #1 either way are pretty slim. She films a music video for Talk That Talk in late January a week or two after she actually releases it as a single. Then, she performs at the Grammys w/ Jay-Z (maybe). Continues her rest until maybe April, maybe even May depending on how long Talk That Talk lasts as a single. I don't want her to be overworked more than she already is, so a few months off and not seeing her perform or doing anything would be worth the exchange of her well-being.
Don't forget the Battleship promo she'll do around May.
We may be even getting some new songs by April/May.
