As exciting as the entire Print Revolution is, I still have a pang of doubt that there is a little too much running before it's learnt to walk. Too many individual parties out for immediate monetary capitalization of this "hip cool new thing" than maybe taking a step back at the long term evolution opportunities that could make it the biggest industrial change since computers.
Not necessarily applicable to all of the players in the market admittedly, like I think AutoDesk's Spark initiative to use an open source public approach, tied together with their knowledge and established history, will keep quality and development pushing in focused directions, while helping build a framework that makes money to continue that community.
