That's what i thought but with Apple these days, who knows what they plan to do.Does it though? Handling iPhone orders and shipments is demanding enough. I don't really see why they would want to do a new iPad on the very same day too. Supposedly it's to protect the secrecy of the A14 chip, but the benchmarks for it already leaked like a week ago. And there there's also the rumours about stores having already received promotional materials and possibly even shipments of the Air 4 itself about a week ago...
I guess we'll know the truth soon.
