Previous results on trans-Planckian collisions in superstring theory arerewritten in terms of an explicitly unitary S-matrix whose range of validitycovers a large region of the energy/impact-parameter plane. Amusingly, as partof this region's border is approached, properties of the final state startresembling those expected from the evaporation of a black-hole even well belowits production threshold. More specifically, we conjecture that, in an energywindow extending up such a threshold, inclusive cross sections satisfy apeculiar "anti-scaling" behaviour seemingly preparing for a smooth transitionto black-hole physics.Comment: 18 pages, 4 figures; typos corrected, references and acknowledgements updated, figures' explanation added in tex
