I think we should look to history to find any clues if Google would release an actual client that would be on par with the dropbox model.

They are notoriously reticent to do anything that installs on a client machine, Chrome being an obvious exception. I'm still skeptical they would release a client but it's definitely within the realm of possibility.

It may be more likely that either dropbox or other 3rd party tools will get into the game and start integrating their offerings with this.

They've had software installing on a client machine after acquisitions though - SketchUp, Picasa and Google Earth.
