I have been hearing about this for the past couple of weeks. It seems Qt will become free even for commercial developers. We actually held back our License Renewal POs after sensing that the rumors were very strong.
Apparently Qt Software will make an important announcement on the 15th of January. So, until then we dont know for sure if this is all true.
Personally though I think making Qt free (for commercial development) is a good thing. The Qt market will become even more big and more work for everyone involved. A lot of companies that were hither-to holding back from embracing Qt because of the price tag will now make the jump. More companies will want to use Qt, that means that there will be more work for everybody.
Keeping my fingers crossed until 15th Jan.
