I hate to say it but chapter 1000 won't be happening this year.
Next week we will get chapter 997 which would be followed by Oda's break.
Chapter 998 spoilers would come around December 11 and then chapter 999 Spoilers around December 18th.
After that we have World shonen jump break and there isn't any schedule release after the WSJ break.
At best we can get early spoilers for chapter 1000 by the end of this year.
