@Drazgoon:
In my opinion Zoro's eye was cut when he got on mihawks nerves, sort of a Kill bill moment with elle and the old master. a warning shot of sorts.
During a SN race to raftel because they had an alliance and the secret to getting there got out, the yonkou are all down (cept for shanks who doesnt give a fuck, he's just chillin watching the new era do their thing) and it's utter chaos everywhere because all of the hierarchy broke down, SHs break through first dreams are accomplished etc. etc. Marines with their new force make it a plan to bring down the new PK, accepting their fates though the other SN accept luffy got there first and serve as allies once again to take on the marines in a final confrontation, fade to black, we never find out what happens after that, flash forward to luffy on his deathbed passing on his hat to ace's son he found on his voyages who's turning 10 shortly, flash forward again 7years and it's Gol D. ace jr taking off from east blue. Oh, and his mentor in the future about haki and shit will be ussopp, i honestly don't see any other SH being as fun a mentor.
Sanji will mostly be like Rayliegh when he gets old or something, white hair, always smoking, acting kool but will lose his kool when he sees a lady, Sanji can understand a situation just by looking at it, his the best swimmer in the crew(can swim in the calm belt lol).. And why would Ace son name be Gol D.? Ace name was never Gol D., Ace son name will either be the mothers last name or Ace last name or Monkey D. Ace jr.
