I think that the rev g it's exactly the same as rev f and maybe just put some component on other place, or just the write on the board, maybe a mistake when changing the date for new prints, F and G are side by side on the keyboard, because looking the pics of rev f and rev g, i didnt see nothing different, thats why they didnt post anything about it. I just post it about the rev g to warn people that could have some boards with rev g on it that isn't a counterfeit, but it's always good look the resistor numbers as ikari said to be sure that's a krikzz one =)
