There's a lot of discussion on that spoiler being a fake, i seen this one which most people are starting to believe it to be the real one
From Battle Franky on AP:
Spoiler seems to be given by Apprentice early, like last week:
ルフｨーVSガープ「わしを倒してから行け！」ルフｨーのギア2がガープにヒット、（ わざと受けた感じ）ガ ープは橋から転落。
そして処刑台にたどり着くルフｨー、エースの手錠を開けようとするが黄猿のビームで鍵 が飛ばさ れる。
そこに処刑人に変装していたまさかのMr.３。能力で手錠を開けようとするが、ついに センゴク の能力発動。
見た目は大仏、巨大化している。センゴクがルフｨー達にパンチする、そのはずみで処刑 台が崩れる、ルフｨー 達は転落しながら手錠を開けようとする、そこに海軍が一斉攻撃、炎の中からエース登場 ！終
Ch. 571: The Gallows
Luffy vs Garp [I'll blow you out of my way] Luffy goes into Gear 2nd and smashes Garp (Garp seems to take the hit deliberately) and is knocked off the bridge.
Luffy arrives at the top of the platform, and attempts to unlock Ace's cuffs, but Kizaru intercepts, knocking the key away with a beam.
Mr. 3, who had disguised himself as an executioner lends a hand to free the locks, but Sengoku finally plays his hand and reveals his ability that makes him grow large (kyojin no mi?)
His appearance is that of a Daibutsu (a large statue(s) of Buddha), he has become huge! Dai-sengoku throws a punch at Luffy, the scaffold collapses bouncing everyone off, Luffy tries to open the cuffs in mid-air (got the key back and/or Mr. 3) the marines concentrate a barrage of fire on them, and from inside a circle of flames appears Ace! Endo.
