Apple released to developers a new test version iOS 12.1 and in her was found the evidence of the upcoming release of the iPad Pro next generation.
In the code of the firmware developers I found a link iPad2018Fall, whereas in the previous version of the firmware was only mentioned iPhone2018Fall. Thus, Apple is planning to release new tablets this fall. Also in the code there was mention of Face ID in landscape view for tablets.
Most likely, the new iPad Pro and laptops will present in October at a separate press event. According to earlier leaks, Apple is working on two new models of iPad Pro with a diagonal of 11 and 12.9 inches. They will be frameless like the iPhone X will lose home button and fingerprint scanner Touch ID, but will get a Face ID.
