I found this on the club site.
"We will have a new 5-piece set of NCV chips designed for the tournament. The chip sets will be available for purchase at $15 per set. Supply limited. Sets may be ordered in advance (must be prepaid) from Pam Focazio, club Promotions Chairperson. Chip sets may be purchased at the club table during the convention too. Chips will be available for pickup on June 27 & 28 at the club table. (Postage added for chips not picked up at the convention. If you aren't attending, add $4.95 insured priority postage for 1-5 sets.)"

Like Jim says, may be best to wait for formal announcement of sales.
I think there are still Orleans and Excalibur sets left from the previous years. Look in the club mag.
