Highly unlikely. They couldn't make it much bigger without either making it uncomfortably close to the device border, or making the device bigger.
> longer battery life
Quite likely. The iPad 2 has better battery life than the original iPad, with a very similar battery. They might be able to get in a process shrink for the iPhone 5, too.
> faster 801n
As I understand it, this would require multiple antennae, so probably not likely for space reasons.
