The NA50 data on the J/psi suppression pattern and the transverse mass spectra in Pb+Pb collisions at the SPS are analyzed. The model predictions for the RHIC energies are formulated. The measurements of J/psi in Au+Au collisions at RHIC are crucial for disentangling the different scenarios of charmonia formation.Invited talk given at the International Workshop ``Ultrarelativistic Heavy-Ion Collisions'', Hirschegg, Austria, January 13-19, 2002 (to be published in the proceedings)High Energy Physics - Phenomenologytext
