Quoted from MikeS:I would love to see Jack keep the rest of the Hobbit details tightly under wraps until it is ready for release
Though I agree in principle with your "Stern" position here in keeping Jack's cards closer to his chest on TH, the distinction between the two business models of course is that Jack requires prepayment whereas Stern does not. Jack's prepayment model would not work without an ongoing release of updates.
