Yeah, that's about right. 12-10-8T/hour for heavy, medium, and lite weights (450, 375, 300T) respectively. Engines should get better over time with PiP upgrades. Wing is an amazing lift generator. The biggest downside is that the -8 gained 30T of weight over the -400. I hoped for less, but Boeing had to add lots of extra structural support for the longer fuselage. Airbus had similar struggles with the A340-600. I understand the wing and engines weigh quite a bit more than the -400 as well. The -8 should get lighter over time and is supposed to meet originally published specs by 2015.
