Current rumors indicate that Apple may actually be planning an upgraded version of the iPad instead of an all new model. The new iPad would launch at the same time as the iPhone 5 in the fall.
The new device from Apple be called the “iPad HD” and will sport a double resolution 2048 x 1536-pixel screen. Apple reportedly would market this in the pro family of Apple products similar to the Macbook Pro or Mac Pro. This product could be marketed towards higher end professionals that need more power than the current iPad can deliver to them.
Both products would launch in the fall, current rumors indicate a September release for both the iPad HD and iPhone 5. These kinds of things make me wonder, why couldn’t Apple build these things into the iPad much earlier, why now?
