If you're lucky enough to have already received your TF700, there's an update slowly rolling out that brings a handful of enhancements to the device. Like with most other ASUS OTAs, a changelog isn't available, but users are reporting increased touch sensitivity, support for 64GB and larger SD cards, an updated camera app, better I/O performance, and other stability improvements.
The update is not yet available on my TF700 at the time of writing this, so we expect it's rolling out on a schedule and will likely begin hitting more device soon.
To see if it's available on your device, head into Settings > About tablet > System Firmware Update > Check Update.
