This is an announcement for the paper "A new isomorphic \ell_1 predual not isomorphic to a complemented subspace of a C(K) space" by Ioannis Gasparis. Abstract: An isomorphic \(\ell_1\)-predual space \(X\) is constructed such that neither \(X\) is isomorphic to a subspace of \(c_0\), nor \(C(\omega^\omega)\) is isomorphic to a subspace of \(X\). It follows that \(X\) is not isomorphic to a complemented subspace of a \(C(K)\) space.
