Nothing in GPL prevents commercial use, and it doesn't limit your 
ability to issue other licenses later. It does not limit the 
author, only the user.

But you have to make sure that all patches you receive are 
followed by a written statements where the ownership is 
transferred to you. The patches makes it a derived work, and then 
you need all the authors of that derived work to agree on an 
additional license.

You cannot revoke GPL for released code, but you can stop 
releasing new versions under GPL.
