Agreed....it depends on many factors, including viewing distance.  I have a 48x72 inch print of a Redtail Hawk taken with a Canon 40D that looks great from "normal" viewing distance.  Up close, it is a little soft, but from 6 or 8 feet away, (normal viewing distance for such a large print), it looks fantastic.  I have done many, large trade show posters that look excellent from their intended viewing distance.
