From my understanding, that is just going to be the start of "Weekly Missions", not Chapter 7.
I base my understanding from the following:
Official BFV twitter: There will be no new chapter but there will be a standalone update this summer with new content, weapons, and game tweaks."

EA-Atic post (a month ago) : "Chapter 6 was the final entry in the Tides of War.".
BFV wiki: "Consisting of six numbered chapters and one non-numbered chapter, Tides of War was end on April 30th, 2020."
@Plucky6922 😞 Thanks.. A shame to hear. But weekly missions are cool as well
