Query: Status and developments of event generators   Event generators play a crucial role in the exploration of LHC physics. This
presentation summarizes news and plans for the three general-purpose pp
generators HERWIG, PYTHIA and SHERPA, as well as briefer notes on a few other
generators. Common themes, such as the matching and merging between matrix
elements and parton showers, are highlighted. Other topics include a historical
introduction, from the Lund perspective, and comments on the role of MCnet.
