Is Gwil Sainsbury returning to Alt J?

Alt-J have posted two photos on their Facebook account, giving rise to speculation that the band's former bassist Gwil Sainsbury may be returning to the band. The speculation has arisen due to photos of the letters "G" and "S" - Gwil's initials.
We can only wait and see whether we have read Alt-J's message correctly, but would love to see Gwil return to the band, which he left for "personal reasons" in January.


Do you think these photos could mean Gwil is back? Let us know in the comment section!
