First thing you will notice is that all CPUs are upgraded to Intel Core i5 and Core i7. That's great but what is even better is that they are not just normal Core i5 and i7. They are, on 15 and 17" MacBook Pros, indeed, Quad Core i5 and i7 CPUs. That's a huge processing power for a laptop.
The next thing you'll notice is that the 13" MacBook Pro is also upgraded to take advantage of Intel Core i5 and i7 but the CPU on 13" models is dual core rather than a quad core on 15 and 17" models. It's a great processor nonetheless!
The other thing that you'll notice is the graphics adapter on the 15 and the 17" models which is now switched to use AMD chipsets. The 15" comes with these variety of graphic chipsets:
AMD Radeon HD 6490M with 256MB GDDR5
AMD Radeon HD 6750M with 1GB GDDR5
The battery life, not much change there but considering the huge upgrade in the CPU, it is pretty impressive the same battery life is provided to customers since you'd be expecting the CPU to consume more power (although that's not always the relation between increase in processing power and consumption of battery).
All in all, these new MacBook Pros seems amazing. Are you going to order one? Have you ordered one already? B)
