Nothing specific has been said about this ship, but production art of it have appeared in
various Star Wars magazines as well as on the Official Star Wars Site. It also appeared
in the Coruscant scenes at the end of ROTJ:SE, which McCallum have said are a bit of a
preview for the Prequels.

There was an old rumor that one of these ships is attacked and chased through
the airways of Coruscant near the beginning of Episode 1. We don't know if this is true,
though. Hopefully, we will have more information in the near future.
