A redesign wasn’t heavily rumored for this new batch of Macs. All things point to a redesign coming at some point next year.
And, I hate to sound line an Apple “apologist”, but the current design of those notebooks are excellent and miles ahead of what’s offered by most competitors. Plus I’d rather get a new Mac now, knowing the current design has had ample time to iron out its wrinkles (ie: keyboard issues).
Except we don't know what keyboard design Apple is using. It was rumored the MBA would revert to the MB keyboard. I am content to wait for teardowns.
