Quoted from PanzerFreak:Yup, all of the drop targets in Hobbit can be individually controlled. Every drop target on Hobbit has its own coil whereas in the case of Beatles, and pretty much all pins, one coil controls the whole bank. I recall JJP saying that the Hobbit is the first pin to have individually controlled drops but not entirely sure if that's 100% true. Either way having individually controlled drops can add a lot of variety to gameplay if they are taken advantage of in code.
I can't believe JJP claimed to be the first to use controlled drops...check out Williams Defender, 15 controlled drops (two coils per drop target).
