In a report to clients — as noted by AppleInsider — Rosenblatt Securities' analyst Jun Zhang says Face ID iPad Pros will ship late in the June quarter.
Apple is expected to update its 10.5- and 12.9-inch Pros with front-facing TrueDepth cameras, enabling Face ID, Animoji, and other 3D-sensing technologies. Zhang thinks the tech giant will ship about 6-8 million updated Pros in the June quarter.
Chances the analyst is right, per the Sellers Research Group: 90%. There’s little doubt that Face ID is coming to the tablet line (at least some models). Both second-generation Pros debuted in June last year. It makes sense for Apple to debut them at June’s Worldwide Developer Conference with availability following shortly thereafter. (WWDC hasn't been officially announced, but rumors are pointing toward June 4 - 8, 2018).
