Apple is expected to preview iOS 6 at the WWDC on June 11 at the Moscone Center in San Francisco. It's pretty much confirmed that they will drop Google Maps in favor of the the 3-D mapping tech they gained from the acquisition of C3 Technologies.
While investigating the new Maps application rumor, TechCrunch‘s MG Siegler discovered that there are "whispers about Siri" coming to the iPad. Many had hoped that the new iPad would feature the voice assistant, but Apple did not include it with the third generation tablet. It's believed Siri was left out because the iPad is not always guaranteed to be connected to Wi-Fi or 4G.
