We present an improved calculation of all B -> light pseudoscalar formfactorsfrom light-cone sum rules, including one-loop radiative corrections to twist-2and twist-3 contributions, and leading order twist-4 corrections. The totaltheoretical uncertainty of our results at zero momentum transfer is 10 to 13%.The dependence of the formfactors on the momentum transfer q^2 is parametrizedin a simple way that is consistent with their analytical properties and isvalid for all physical q^2. The uncertainty of the extrapolation in q^2 on thesemileptonic decay rate Gamma(B -> pi e nu) is estimated to be 5%.Comment: 10 pages; talk given at Continuous Advances in QCD 2004, Minneapolis,  May 200
