Explain please. It would seem the the ARM Cortex A9 multi-core has been available for license from ARM for over a year:

Granted that the usual ARM chip manufacturers may not plan to have A9 chips until 2010, remember that everyone is assuming Apple bought PA Semi to have their own in-house ARM chip design shop. This year and the anticipated third generation of iphone have seemed for some time like a reasonable place to see an Apple / PA Semi designed ARM chip introduced. Given that Apple has a long time inside relationship with ARM (being one of the founding partners of the current ARM and a major investor) and that they were obviously working with PA Semi well before the purchase, it does not seem unreasonable that Apple could have access to an A9 multi-core finished product well ahead of the rest of the industry.
If Apple does have an advantage getting an A9 chip to market first and if the ARM hype about A9 is even half true and if Apple does a good job taking advantage of all that power with iphone OSX 3.x, then all those 'iphone killers' are probably going to get pretty well killed.
