Here are the rumors that we are anticipating for WWDC on Monday:
iOS – well this has been confirmed but we still do not know the details
Apple Maps -Apple will drop Google Maps for their own version that will have text to speech directions
Siri for iPad – Finally siri support for iPad. Not sure why it is already not on iPad 3, maybe it was iOS 5 that didnt allow it for whatever reason
Macbook Pro -To be updated with the ivy bridge.
iPhone 5 – This would be the biggest surprise as we are pretty sure this is a fall release and the 4s is still selling like crazy.
