I present a personally biased view of the present status of seismology of δ Scuti stars. While much thought has been given to develop new tools for mode identification, the required cross-calibrations between them are difficult. I suggest to pay more attention to target selection, since the objects which have the best chances to be successfully modeled - unevolved, slowly rotating δ Scuti stars - are poorly observed. In the light of an upcoming large multi-site campaign on the only well investigated representative of this class, WET 0856 = CD-24 7599 = XX Pyx, I estimate the size of some spurious results which can affect data analysis, in particular those caused by passband mismatches of inhomogeneous equipment used in worldwide observing campaigns. I find that they hardly influence the results for δ Scuti and roAp stars, but they can become dangerous for high-amplitude DA pulsators.
