Definitely. The mempoor can definitely be flooded again like we had at the end of last year, but chances are it definitely will be less flooded due to the increase on SegWit adoption(unless we see a significantly bigger hype compared to last year's).
It really surprises me how many people and services are still not using Segwit though.
Even the Blockchain.info(now .com) still doesn't support segwit. Like what the hell?
