I imagine the protracted development time is at fault. The guy from Penny Arcade wrote a blog post where he said that he tried a prototype a year ago, so presumably this has been in development for at least a year and a half. Probably the 9xx was the best they had at the time and when the 10xx was released they were too far along in development to swap it out. The next one should have it though.
