Thanks to the excellent energy resolution, high efficiency and versatility, bolometric detectors are primed for the search of neutrinoless double-beta decay (0νDBD). The most advanced bolometric experiment, CUORE, is studying the 0νDBD of 130Te using a 741 kg array of TeO2 crystals. CUORE points to a 90% CL sensitivity on the half-life of 0νDBD of 9.5 × 1025 yr in 5 yr, corresponding to an upper limit on the neutrino Majorana mass of 50–130 meV. This sensitivity will allow to touch, but not to explore, the region corresponding to the inverted hierarchy mass scenario. In this document I present the status of CUORE and the possible upgrades of the bolometric technology in view of a next generation experiment.
