  An analysis of all available data (CELLO, CLEO, \babar) in the range $[1\div
40]$ GeV$^2$ for the pion-photon transition form factor in terms of light-cone
sum rules with next-to-leading-order accuracy is discussed, including
twist-four contributions and next-to-next-to-leading order and twist-six
corrections---the latter two via uncertainties. The antithetic trend between
the \babar data for the $\gamma^*\gamma\pi^0$ and those for the
$\gamma^*\gamma\eta(\eta')$ transition is pointed out, emphasizing the
underlying antagonistic mechanisms: endpoint enhancement for the first and
endpoint-suppression for the second---each associated with pseudoscalar meson
distribution amplitudes with distinct endpoint characteristics.
