We’re betting on the arrival of Tiffany & Co., whose presence at Westfield Montgomery Mall would help pave the way for a whole new group of similarly high-end retailers. Mall management will confirm only that a “luxury jeweler” is on the way, and Tiffany remains tight-lipped about its plans. But our Mall Crystal Ball has been pretty accurate so far: This is one of three predictions we made back on May 29 (you can read that issue here) — and two of them (Lululemon and the Microsoft Store) have since come true.
