Apparently when using Japanese Wordplay (Goroawase specifically) 1127 can be a Pun on "Hito-Tsunagi".
Which is how One Piece Treasure is referred to in Manga (You can search for it in Wikia)
Also in Noland's Flashback, 1127 is marked as the Year He reached Jaya with his King & Soldiers, only to find Golden City have disappeared.
Not only it could be a Hint by itself, but We also know that Noland found Jaya in Year 1122, and Chapter 1122 showed us a Teaser of Joy Boy
This is what i remember from what i read, but apparently Chapter 1127 is expected to have a Major Hint/Teaser about One Piece Treasure.
(After all, Joy Boy is clearly connected to Elbaf Land and this SH Disappearance Situation is similar to when Shandia mysteriously vanished)
