Let's see.... Ships 278,281,283,284,285,286,287,289,290... That makes nine. Ship 288 is in MCO having surgery now. Ships 279,280,282 will follow one at a time (not necessarily in that order). When delivered, Ships 291,292 will be similarly equipped before they enter service. That totals the 15 initially planned to have the Winglets. It's almost a certainly that others will be added later. When and how many remains to be determined.
