The company has discontinued the older 10.5-inch iPad Pro from 2017 but the 9.7-inch iPad introduced last year will remain in the lineup. 

Apple often introduces new products in March. At last year's event, Apple delivered a refreshed edition of its entry-level iPad in addition to some education-friendly software initiatives. That today's announcement was made by press release suggests that the company wants to keep the focus of next week's event solely on its new video streaming service.
