IBTimes is reporting that the next generation of the iPad will be called the iPad 2 Plus.  While not many details were talked about, it was interesting that the main upgrade might be a Retina Display upgrade to the device.  It would be somewhere around 250-300 ppi vs the current 132 ppi, the iPhone sports 326 ppi.  If the rumors are correct it could reduce the shipments in the fall of the iPad 2 as consumers naturally will begin waiting to see what comes out next.
