It will feel like super stretching by Oda if he wants to end Act 3 on the 1000th chapter.
Scabbards played their funny show for too long.
I think we are trying to correlate the ending of Act 3 or the mid Act updates and it at all being near 1000.
I dont think chapter counts will be that perfect. Right now, Act 3 is ~36 chapters long. All im saying is, if it ends at 994/995, I dont expect Oda to stretch the mid act stuff till 1000, just as I dont expect Act 3 to be stretched that far either.
That being said, I dont think its impossible for Act 3 to last 3-4 more chapters till 997/998. IF Oda in fact has something big planned for 1000 outside of Wano, then I see this as being how its done. I dont think he'd spend more than 2-3 chapters away from Wano
