The Belle-II experiment is expected to collect large data samples at the Upsilon(4S) and Upsilon(5S) resonances to study primarily B and B-s mesons. We discuss what other data above the B (B) over bar threshold are of interest. We propose to perform a high-statistics energy scan from the B (K) over bar threshold up to the highest possible energy, and to collect data at the Upsilon(6S) and at higher mass states if they are found in the scan. We emphasize the interest in increasing the maximal energy from 11.24 GeV to 11.5-12 GeV in the future. These data are needed for the investigation of bottomonium and bottomonium-like states.
