Yeah I can't wait for someone to tear this thing down!

There is no need to donate. They buy them for marketing.

Regardless whats in it, the faster speed will be great!

Well the reviews have looked hopeful for sure.

I can see Apple using Dual Cortex-A8s as a possibility. Didn't they have the option of dual PowerPC processors in the MacG3/4/5s when dual processor setups were mainly used in servers at the time?
If the above information is incorrect, please correct me and accept my apologies. I'm not too familiar with Apple products offered back then.

agreed on knowing the truth! lol

So like the OP said, its possible that Apple's shoved a dual-core A9 in there that will run at 800MHz in its most power efficient mode -- but like krosis pointed out, a dual-core processor can be more power efficient than a single-core at the same speed if its used for a smaller amount of time to perform the same task. Couple that with, say, the ability of the processor to clock up from 800MHz to 1GHz under load (which doesn't happen often, honestly..) and some power-management tweaks under the hood and you're looking at a faster beast with similar power performance to the iPad's SoC. Apple could get away with using off-the-shelf Cortex A9's if they tweaked the system in just the right way.
Another possibility: iPad 2 runs in 1GHz dual-core mode until 20% of the battery is left, and then clocks down to 800MHz.
Another possibility: for the most part, the dual-core processor relies strongly on a single core most of the time and lets the other core sleep except when under heavy load, giving the iPad 2 the ability to run with all the speed of the single-core we're all used to but have the opportunity to perform faster under load.
And even if it could only achieve 95% as much battery life as the single-core, I doubt Jobs would go up on stage and say 95% -- he'd say 100%. It's good PR.

Hmmm A5 seems like a big graphics upgrade not speed. So basically when iOS 5 comes out it won't be that slow and have majority of the handy features

Either waits great to get soMe speed improvementsYou don't like the iPad because you don't have one!

Speed baby. But does this mean the price will rocket like the gas prices?"Time circuits on...flux capacitor...(gulp)...fluxing"
Please read again I only give one warning - thanks!
