The 9570 has basically the same specs as the Storm 2 with an upgraded 5MP camera, 512MB of RAM and with the new BlackBerry 6 OS under the hood (bringing the new WebKit browser along with it). The SurePress technology is back again. Still, there is no talk of a 1GHz processor, a Mobile Wi-Fi Hot Spot and the LTE connectivity that the Storm 3 is expected to feature.
So looking at the situation as it appears to stand, the 9570 looks to be a BlackBerry Storm 2 Refresh-call it the Storm 2.5, and the super hot specs of the Storm 3 might be something we don't see until next year.
