  The potential of the ALICE, ATLAS, CMS and LHCb detectors for the measurement
of quarkonium in heavy-ion collisions, both in nucleus-nucleus (A-A) and in
proton-nucleus (p-A) interactions, in the years 2015 until about 2030 in the
LHC Runs 2, 3 and 4 with larger statistics and detector upgrades is described.
A selection of newly available observables is discussed.
