Ipad mini?

the conclusion from the most Apple's devices, I come out with simple formula the combination Apple innovations to create a new device among it devices. 

Mac Pro + MacBook = MacBook Pro

iPod + Phone = iPhone

MacBook + iPad = MacBook Air

iPhone + MacBook Air = iPad

but if


iPad combined with retina display technology, it may be iPad mini?

iPad + retina display = iPad mini?

just suggestion for Apple Inc.
