Seems like Naoki Yoshida wants to avoid a buggy launch and deliver a complete product. He was also mentioning FF14 in the same sentence since Endwalker is coming up soon.
Not NEWS news, but it will do a lot to the reputation of the series to have a second quality product after FF7 Remake in the singleplayer games.
Otherwise it's not to be taken at a potshot at anything , he just mentioned it because some FF14 fans are accusing him of abandoning FF14 in favor of FF16 ever since its announcement.
