Not true fellas. The 1991 series WAS going to be discontinued, but someone persuaded Colt to change their minds. I actually called Colt a few days ago to ask them about this and I was told that the 1991 series WAS NOT going to be discontinued.
However, the original fax from Colt did include the 1991 series on the discontinued list, so it would make sense that many dealers do not know that it hasn't been.
I too have seen their prices skyrocket. When I bought my 1991, it cost me about $425. I now see them going for upwards of $600 just because people think there will never be any more of them. Wait a while and prices will hopefully come back down to Earth.
