What does it mean for the tri-core A8X now that the A9X has been revealed to be a monstrous dual-core CPU? Will iOS app developers properly code their apps for the three cores or has the iPad Pro completely scuppered iPad Air 2's future prospects? Will any app take advantage of more than two threads? Will the A8X get a second wind if the A10/A10X turn out to be tri-cores or quad-cores next year? How will A8X fare in light of remaining the only CPU in iOS history to have more than two CPU cores?
