We show that in sudden hadronization of QGP a non-equilibrium value of the pion phase space occupancy parameter gamma(q) > 1 is expected in order to accommodate the entropy excess in QGP and the process of gluon fragmentation. When gamma(q) is near to its maximum allowed value, pion overabundance is shown to arise at low m(perpendicular to), where the charged pion asymmetry is also amplified. These effects are considered and we show that their magnitude suffices to explain pertinent experimental data obtained in 160-200 A GeV Pb- and S- induced reactions. (C) 2000 Elsevier Science B.V.
