We're used to seeing the online tech world go crazy with rumours and speculation in the days before Macworld, but this year a new element has been introduced to the mix.

Steve Jobs' keynote speech, that he is due to make on stage at the Moscone Centre in San Francicso on Tuesday 15th January, has apparently been leaked via Wikipedia.

With highlights including a 16GB 3G iPhone, details of the SDK for the device, a 13-inch 0.8-inch thick redesigned MacBook and direct YouTube for Apple TV, it would not be a dull keynote if it's all true.

In its entirety, if the sources are to be believed, here is what Monsieur Jobs is to cover during tomorrow's time on stage:
