At launch, Playcast expects to have around 100 AAA games like Batman Arkham Asylum, Dirt3, and Sonic Generations in its library, with a ten percent title churn in each package every month to keep things fresh.
That could change, though, as dirt-cheap 3-D printers like the Printrbot or new MakiBox simplify the technology and put it in more people's hands and home offices.
