This is an announcement for the paper "Diametral diameter two properties" by Julio Becerra Guerrero, Gines Lopez Perez and Abraham Rueda Zoca.

Abstract: The aim of this note is to define a generalization of the diameter two properties in terms of the abundance of diametral points. We shall also analyze the stability of these properties under $\ell_p$ sums and the problem of inheritance to subspaces.
