  Detailed predictions for the scaled pion-photon transition form factor are
given, derived with the method of light-cone sum rules and using pion
distribution amplitudes with two and three Gegenbauer coefficients obtained
from QCD sum rules with nonlocal condensates. These predictions agree well with
all experimental data that are compatible with QCD scaling (and collinear
factorization), but disagree with the high-$Q^2$ data of the BaBar
Collaboration that grow with the momentum. A good agreement of our predictions
with results obtained from AdS/QCD models and Dyson-Schwinger computations is
found.
