I agree. Just look at the way Google slowed down the incrementally increasing storage of Gmail. It's been some time but it's still lagging after they did a major "bump" some years back. There might be a lot of applause at the beginning but being able to knock Dropbox out of the game will take serious effort.

I think GDrive will help DropBox more by offloading their freeriders to Google. People seeking a better premium experience (and less risk of say losing all their GDrive contents because their Google+ got suspended) will likely find DropBox appealing once they realize the convenience of a service like this.
