I wonder whether one area that will benefit from 64 bit very early and will improve our user experience is speech recognition (Siri etc). That takes a lot of CPU power which is why heavy use is made of Apple's servers to help with the processing. If more processing could be kept on the device then it would make the user experience significantly better in bad reception areas and would also save Apple some money since it would reduce the load on their data centre servers from processing voice analysis tasks. Even if Apple's servers are still involved having more in-device CPU power might allow the data sent up to the servers to have undergone more sophisticated pre-analysis and compression so that less data needs to be transmitted to the servers and those servers have less work to do on it to complete the analysis once it's arrived.
Got a tip for us?

the a7 actually matches quite a few lower end 64b desktops. and since when does an "announcement" equal an actual product in the stores? now if the galaxy was released next week with a 64 bit chip i would agree with you.
Okay, to be more precisely:
„All (marketable) 64-bit architectures are designed to provide backwards compatibility with 32-bit apps.“
When Apple says that "moving to 64-bit will increase performance for all apps" they aren't necessary referring to the benefits of the 64-bitness, but more to the new ARMv8 instruction set, that just happens to also be 64-bit. The new ARMv8 ISA includes more and larger registers, accelerated encryption, virtualization support, better facilities for multicore, branch prediction, load/store operations, better integrated SIMD, ans more. All applications will benefit of some or all of these features, and even if you don't code for them yourself, Apple does, and their frameworks will make use of them.
