It really wouldn't surprise me. I don't know about during the timeskip, but there will definitely be a TON of filler when they are on Fishman Island. The only potentially helpful difference between the OP timeskip and the Naruto timeskip is that the OP one gives a better idea of what the characters are going to do. Nami's going to study unique weather, Chopper's studying medicine, Franky's learning about secret futuristic technology. All we really know about the events during the Naruto timeskip is that he traveled around with Jiraiya and he got a bigger Rasengan. If there are episodes during the timeskip, it will be slightly better than Naruto's.
