Thats my favorite chip set. Harrah's hasn't done one since the $5.00 Dry Heat chip. There were 4 in the $2.50 series. They put them out 4 years in a row, from 1998 through 2001. then on the 5th year(2002), they released the $5.00 Dry Heat chip.

Your guess is as good as anyone's as to if or when they would release another. I can tell you this, there will be an awful lot of people very happy to see it come out.
