That is a great question. The PS express organizer and Uploader are specific to Photoshop.com. They will continue to work for un-migrated users until the end of the transition period. At the conclusion of the transition period, the Organizer and Uploader will no longer be used. Revel has the ability to upload and edit photos and after the transition period, you can use this if you choose. At this point in time, you can continue to use the PS editor as a stand alone editor for photos on your device if you choose to.
I hope that helps.
