10.5″ iPad Pro Entering Limited Production, But Launch Remains Unclear

Joe Rossignol:

At this point, however, it remains unclear whether the 10.5-inch iPad Pro will be announced later this spring, at WWDC 2017 in June, or in the fall or later, as rumors are lacking consensus.

If the 10.5″ iPad is going to showcase a new iPad design language, perhaps akin to the new iPhones, then I would assume it will debut in Autumn, along with or after the iPhones.
