Siri has been made to run on older iOS devices some time ago. It was reported by MacRumors that special hardware is what sets the iPhone 4S as the exclusive device for Siri. Enter the new iPad.
The new iPad supports voice dictation, which, to me anyway, is a clear indicator of at least some of this earSmart technology making its way into iPad 3. Additionally, the new iPad has some sort of access token to Apple's servers, given the voice dictation feature. As discussed by answers to my question here, the new iPad is connecting to Apple servers for voice processing. Additionally, Voice Dictation would imply that the new iPad has access tokens for Siri's servers.
So, we have the hardware, and we have the token. The new iPad should be able to run Siri, pending an update from Apple or the jailbreak community.
Is this thought process correct? Have I missed anything?
