It is probably too early to draw conclusions from the evidence accumulated so far. However, it is becoming clearer that the small scale gas morphology indicates that the "early- type" galaxy population is far from "quiescent". Same can be said for "cD" galaxies in small/sparse groups. This would indicate that there is ground for more detailed studies of the high energy emission in galaxies; these might reveal unsuspected phenomena like shocks that are crucial for our understanding of the evolution of these systems. The multiwavelength approach is the only one that can provide a complete picture of all the forces at play, and the study of the gaseous components, though complex, has a very high potential for easy discovery of extreme, but perhaps not uncommon, phenomena.
