Whole Foods opening in Metuchen
You've got a long wait. Wegmans announced plans in July 2012 to build a store in Hanover, NJ; the site is listed as date TBD on their Store Opening schedule. Whole Foods announced plans in November 2012 to open in the current location of the A&P in Morristown, NJ; latest news reports cite likely opening late this year or sometime in 2015.
Aside from town planning/zoning board approvals and other logistical stumbling blocks, one supermarket chain will frequently bring court actions to stall their competition's efforts and secure another year's profit for themselves.
