This is an announcement for the paper "A note on fragmentability and weak-G_delta sets" by V. P. Fonf, R. J. Smith and S. Troyanski.

Abstract: In terms of fragmentability, we describe a new class of Banach spaces which do not contain weak-G_delta open bounded subsets. In particular, none of these spaces is isomorphic to a separable polyhedral space.
