Abstract: We predict several new bound states and resonances for B-pion, B-Kaon, and B-D S-wave elastic scattering, within the same model which was recently employed to explain the D*sJ(2317)+ meson. In the charm-nonstrange sector we find a (virtual ?) bound state close to the B-pion threshold, and moreover two nearby resonances of comparable width in the range 5.9 to 6.1 GeV. We obtain bound states B*s0(5570) in b-sbar and B*c0(6490) in bbar-c, as well as resonances at higher energies. No JP=0+ states are found at 5.6 GeV (in bbar-u/d), at 5.7 GeV (in b-sbar), or at 6.1 GeV (in bbar-c), where they are predicted from pure confinement.
