I think Sanji will get his big moment against Kizaru. How well he does will be revealed, but it's his job to stall to protect his allies.
Franky getting the light-gloves and Zoro finishing Lucci could definitely lead to a Straw Hats teaming up against Kizaru, but for now Sanj's the only one who can touch him and is available, so it's all on him. Luffy will return soon enough, but that'll likely be against Saturn.
I hope we get Sanji using Ifrit Jambe and his top speed, I know Oda could easily off-panel it and have him struggling when we return, but I have faith in Sanji, especially given that this acts as an opportunity for him to try and live up to his claims at Thriller Bark. Obviously that was exaggeration for the sake of stepping up, but with Kuma present and it being a matter of protecting against the government and Marines, it could be a decent call-back.
It could also be for the sake of the crew as a whole, to try and rectify their loss to Kizaru at Sabaody, especially with Kizaru wanting to see just how much they've grown, if Sanji is incapable of doing anything, it ain't a good look. Luffy proved himself, now it's time for Sanji to show he's grown since then.
