Yup, but I doubt that we'll see all these performance increases delivered to the next iPad because Apple needs to worry about more than just performance, they need to keep one eye firmly on power consumption as well. I wouldn't be surprised if they'd like to reduce the size of the battery in the next iPad so as to trim some weight off it and that means delivering whatever performance they're targeting at a lower current draw. Obviously the increased IPC of the Cortex A9 will be there, and possibly the Apple engineers will tweak the architecture some more to raise that IPC even further, but I'd be surprised if the clock speed was set much above the current 1GHz, maybe 1.2GHz maximum because, coupled with a 1.25 gain in IPC, that still gives a 50% performance boost over the A4.

In essence, I agree with you. Apple has no incentive to give the most performance at the start when they can incrementally improve it and squeak out more generations of the same basic core. Wouldn't surprise me if we saw a launch 45nm core followed by a 32nm revision that ups the clock speed and/or core count.
