is there going to be a new buffy the vbampire slayer and when?

There have been rumors recently that Kuzui (who have the rights to the original Buffy movie with Luke Perry and Kristie Swanson) plan to remake it without Whedon. But there was a lot of criticism of that so they may not. As for more of the Buffy TV show. The show is done. Joss Whedon has continued the story in comic book form which he's said is the official story of Buffy Season 8.
