Thanks bendlinglight!

Unfortunately or fortunately, depending on your desires P2fanboy, there is only one cut. Hopkins said it was literally his first working cut that premiered. That's all he had time for!
Production for Predator 2 started February 1990. Director Stephen Hopkins was expecting a Spring 1991 release but Fox moved it up to a November 1990 which gave him an incredibly small amount of time to finish the movie. 10 Months! It's ridiculous, right? Because of that ridiculous small amount of time, Hopkins said pubically that it was his
first working cut that premiered and he would have edited differently if he had more time. It was so rushed, optical effects were added 3 times between batches of film prints. So technically, depending where you lived, the optical special effects could have been better, more robust, or less.
I think Hopkins caused all this darn confusion when he said in the commentary many years later that Predator 2 was their first NC-17 case and had to go back with cuts over 20 times. I think it's important to differentiate a cut from cuts. Hopkins had to make cuts to gore to avoid an NC-17 rating, but that's done in house during editing. Directors have access to lawyers, producers and ex-MPAA review board members paid by Fox to review target scenes, rating score them based on current MPAA guidelines, plus make recommendation cuts to make a target rating... all during the editing process against a high pressure deadline. Hopkins didn't actually have time to make over 20 versions of the movie, time to make over 20 working cuts and send them each off, one at a time, to a MPAA board for review, each with a musical score in place. There was just no time for that.
I guess what I'm trying to say is it would appear there is no working gore unrated cut, with extra gorey scenes, complete with score in place, on the shelf waiting for release.
