000000537 520__ $$aWe give a short overview of existing branching fraction measurements of charmless semileptonic B meson decays of the form B -> Xu l \nu, with Xu being \pi, \rho, \omega, \eta or \eta'. We focus on results from Belle and BABAR collaborations. We report prospects for measurements and estimates for |Vub| determinations in B -> \pi l \nu decays at Belle II. With the full expected Belle II dataset, 50 ab−1 of integrated luminosity, the estimated errors on |Vub|, including expected improvements in Lattice QCD calculations in the next decade, are 1.7 % and 1.3 % obtained with the tagged and untagged method of companion B meson reconstruction, respectively.
