I've been recently following Wlad on his twitter and fb accounts.
He has a lot of activities going on - working on his brand and many other projects that don't have much to do with boxing.
I really think he will announce his retirement in a few weeks time.
word is the rematch will be Oct 28th according to Dan Rafael at espn.
When the IBF detailed the exception for the AJ - Wlad fight they said this:
1. If Wladimir Klitschko is unavailable for the rematch on October 28, 2017, the fight shall be staged no later than December 2, 2017.
That pretty much confirmed that the planned date is October 28th to everyone.
I am leaning towards the fight happening, its just too much of a BIG FIGHT for any fighter to turn down if? They still have the ability to lace the gloves up! Wladimir Kiltschko i believe will want to ride the crest of that wave once again! The Build up, the internal and external preparation! (The feeling of being alive!)........None of his current projects will ever be able to replace boxing! and he is one of the very few fighters in my opinion who genuinely LOVE's boxing! (He even stated in during his preparation for Joshua? I am in love! Love is obsession! haha).
