New analysis of the heavy, neutral MSSM Higgs bosons H and A production at the Photon Collider is presented for MA = 200, 250, 300 and 350 GeV in the parameter range corresponding to the so called "LHC wedge" and beyond. The expected precision of the cross section measurement for the process gamma+gamma->A,H->b+bbar and the "discovery reach" of the Photon Collider are compared for different MSSM scenarios. The analysis takes into account all relevant theoretical and experimental issues which could affect the measurement. For MSSM Higgs bosons A and H, for MA = 200-350 GeV and tan(beta)=7, the statistical precision of the cross-section determination is estimated to be 8-34%, after one year of Photon Collider running, for four considered MSSM parameters sets. As heavy neutral Higgs bosons in this scenario may not be discovered at LHC or at the first stage of the e+e- collider, an opportunity of being a discovery machine is also studied for the Photon Collider.
