In the past 24 hours it seems that some percentage of signaling mined blocks have changed from BU to Segwit. (4% over the total, 12% change from BU to Segwit).

BU: 36.1%
Segwit: 31.9%
8MB: 5.6%
Maybe its just an oscillation... but worth pointing it. (ANTPOOL, representing almost half of BU signaling, is still doing it, though).
