Know we know why Walt Mossberg referred to the new Storm as Storm2 and not Storm 2 in his review. The official name for the new touchscreen BlackBerry is Storm2. RIM just pushed their new Storm onto the homepage and offers a closer look on what is new.

The BlackBerry Storm2 9550 is offering a new touchscreen, Wi-fi and 2GB of storage.
The measurements of 4.43 inches (112.5 mm)x2.45 inches (62.2 mm)x0.55 inches (13.95 mm) stayed basically the same compared to the Storm.
RIM says about the next generation SurePress technology found on the BlackBerry Storm2 that it provides better typing accuracy and a more tactile feel.
You can type now on a virtual full QWERTY keyboard in portrait or landscape mode and touch two areas of the screen at once to select multiple items.

The Storm2 will be available from Verizon Wireless in the United States and the Storm2 (9520) has just been announced from Vodafone in the UK.
