  The supersymmetric Poisson Sigma model is studied as a possible worldsheet
realization of generalized complex geometry. Generalized complex structures
alone do not guarantee non-manifest N=(2,1) or N=(2,2) supersymmetry, but a
certain relation among the different Poisson structures is needed. Moreover,
important relations of an additional almost complex structure are found, which
have no immediate interpretation in terms of generalized complex structures.
