We describe multi-particle production in ultra relativistic heavy ion collisions at LHC within the chemical non-equilibrium statistical hadronization model. We find, that the effect of much higher available energy of the reaction compared to RHIC, is fully accounted for by only one quantity, the total entropy content of the fireball. The hadronization of the fireball at LHC occurs at nearly identical intensive physical bulk conditions for all geometrical centralities considered, and these conditions agree with those seen already at RHIC.
