The kanji for Sanji's Diable Jambe is 悪魔風脚, which literally translates to Devil Wind Leg. Sanji's newest attack is called 魔神 風, which translates to Devil Wind, so they practically have the same meaning but written differently.
One thing to note is the kanji for leg is no longer there. Hell Memories is notably the only Sanji's attack that doesn't start with him saying Diable Jambe. I suspect it's because Hell Memories fire covered his entire body and not just his leg. Seeing how the new attack also dropped the leg part, I assume this new attack also has fire covering his entire body and not just his leg.
Finally, 魔神 風 can be read as Majin Fuu, which sounds very similar to Majin Buu. I always wondered why Oda added the kanji wind for Diable Jambe even though it is a fire based attack and not a wind based one. Oda might have already planned this to be Sanji's upgrade from the moment he introduced Diable Jambe, because Sanji outburst in Thriller Bark and subsequent Hell Memories, is a power that is based on Sanji's anger. They are likely a tribute to Super Saiyan. 魔神 風 might just be another reference to Dragon Ball.
Found this on reddit, this Devil Wind mode looks to be a full body power like HM and Sanji ignited it by combining all his skills. It's like a stronger version when he first spin his body to ignite DJ.
