Our AS has no ghosting issues.
At CAX this year marco had a lot of new games on display. There were about 4 Aerosmiths, all looked perfect and somewhere around 10 Star Wars, two of which I saw ghosting inserts. Neither were terrible, just slivers on a couple inserts each.
Other than that personal observation... just general noise in the forum, haven't seen many AS complaints but SW seems to be a little more active in that department.
