I strongly believe the iPad Pro 2 9.7" & 12.9" will be released sooner rather than later. Apple would lose a marketing advantage plus research and development on the A10X processor. The next iPhone 8 will have a A11 processor in the fall so the clock is ticking for Apple to release these new iPads ASAP. I cant see them wasting time, money, and reputation releasing the new iPads in the fall with the A10X. I am assuming that the A11 will be more powerful than the A10X.
