Nah, doesn't make sense to end like that. Looks more like a set up to the end.
Reiju's powers are left to be used, it might even have something to do with his plagues, Judge's powers are also left to be used, Queen made very clear he can do anything Sanji's family can.
Queen didn't exactly react to Ifrit Jambe's offensive power like Jabra did to Diable Jambe.
Oda, for some reason, is playing with numbers using Sanji.
Chapter 931: Sanji uses the suit
Chapter 1031: Sanji destroys the suit
Chapter 935: It's called "Queen", introduces Queen
1035: Sanji vs Queen finale, Queen defeated confirmed
So everything points out that the fight is not over yet, there is a huge potential left for this fight given Sanji and Queen's arsenal and overall capabilities.
If Oda decides to end the fight like that, it is a bit underwhelming because it will feel like it was a wasted potential, and King will most likely follow the same route.
Oda has been treating King and Queen pretty differently compared to the rest by far, and for obvious reasons, they are Zoro and Sanji's opponents, the wings. So lets hope he keeps being consistant and gives us the epicness they deserve.
Given the similarities this arc has with Enies Lobby, thats what might happen again, you can check by yourself:
Chapter 414 "Sanji vs Jabra": Sanji vs Jabra intensifies.
Chapter 415 "Heat Up": Climax, final clash, Jabra is defeated.
Chapter 416 "Zoro vs Kaku": Zoro vs Kaku intensifies.
Chapter 417 "Asura": Climax, final clash, Kaku is defeated.
