Storm 2 is definitely being supported. There is a 6.0 O/S for Storm 2 coming out and there are plenty of peeks at it floating out there in cyber space. Just do a "WES 2010" search.
O/S 6.0 retains the rigid, blocky appearance of its predecessors but it has some cool new pop up menus that give it more flexibility. Check it out. http://www.youtube.com/watch?v=DlO8KMv7Bx4
