  We show, by means of a simple compilation of the available experimental
results, that the pT-spectra obtained at RHIC and SPS are strikingly similar up
to pT ~ 1.5-2 GeV. In fact, the discrepancies between various experimental
groups working at the same experiment are of the same size as the differences
between RHIC and SPS. Our observation is complementary to the well known fact
of the equality of the measured R_side and R_out HBT radii at RHIC and SPS. In
essence, it points out that the transverse size of the firecylinder and the
strength of the transverse flow are not significantly changed between SPS and
RHIC. This suggests that a saturation mechanism is effective already at SPS. We
also point out that the dominance of protons over pi^+ at large pT can be seen
not only in the RHIC data, but already in the SPS data.
