Hasn't been announced on her official page formally, but it was mentioned on the last page of "sankyu! vol. 2", so ---
Live album of the "FOLLOW ME UP" tour to be released in summer. The recording was presumably made at the tour finale at Nakano Sun Plaza, though I hope they include "kuuki to hoshi" which she performed only in 2015. There were some handheld cameras too, so hopefully we'll get some footage as well.
It's been over two months since the tour ended, but I attended four of the concerts - wonderful tour, and shows just how much she has grown as a live performer over the last five years since she started touring regularly. Great setlist too, lots of oldies - I was surprised at how many songs from "Lucy" were featured.
EDIT: Officially announced at her HP, along with a new single, "Million Clouds", to be used as the theme song for the anime "amanchu!" starting from July.
