For me, the best thing she could do (and my heart cries at the thought we could not get new Taylor next year) is release TS6 in 2017, because if she releases it in 2016, she will be more than overexposed, it would do big damage to her, but she can't stop with 1989, it is still so fresh and has still SO MUCH life in it! So the best chance (for her
) is: release in 2017.
