Actually several, but lets start with the two I like the most...
First the new "Raging Judge Magnum"...3 or 6 inch barrel, 6 rd cyl, shoots 454 Casull/3".410/.45LC. I think I will get a 6" barrel as soon as I can get my hands on one.

Then a new Rossi Rifle with a Judge cyl. the "Circut Judge"
The waiting list on one of these is already well into 2011.

There are actually several new Judges on the Taurus site including an ultra-lite with a seven round cyl so look around.
