Gear Ratios for G56 and 6.7? Same as 5.9?

Does the G56 6-speed hand shaker have the same gear ratios mated to the new 6.7 versus the 5.9?

Just curious because I read somewhere that it changed (as in a better overdrive).

Also--does the exhaust brake also come with the 6-speed, or is the 68RFE auto required?
