In my opinion, it's very reliable in the light of some clues such as this : https://www.youtube.com/watch?v=d4e0W26HZ4U (about 4.00) where a guy from SJC talks about a new drum kit ready to send to Tre Cool. Also, Tre has published this photo on his intagram profil 5 weeks ago : https://instagram.com/p/7ZYVdmRy6F/?taken-by=trecool Finally, a french guy has got the privilege to meet Billie Joe in August, at Broken Guitars, He asked about the next album and BJ told they have "some" pieces and should not delay to return to repeat, to put it in shape. Something happening...Secretly but surely.
