Stardock to Roll out Impulse Phase IV in September on the Impulse Website previews upcoming changes to Stardock's online service and points the way to another preview on Kotaku. They say the new version will roll out next month, and word is that besides adding many more games and enhanced social networking features, they will finally be dispensing with the need for a client for downloads:

The new version of Impulse comes with an update client that allows users to associate their purchases with a single account – a user who gets a new PC can then install Impulse, logon, and then download and install all their Impulse purchases easily. It also includes a new store designed to handle the vastly increased library of games, applications, and utilities that have been being added over the past few months and to prepare for this Fall when back catalogs from major publishers are being added.
