Again pure speculation. But if Apple were to start supporting 24/96 (or dare I dream 24/192), I think its safe to assume it will be tied into the firmware/OS.
I saw a list somewhere that showed what iDevices could run IOS7, but I'll be damned if I can find it now. Think its iPhone 4 and up, iPad 2 and up, and iPod Touch 5th
