I have that guide and I reference it quite often. It does seem that more times than not here lately it has been on the low side, so maybe a number of prices will be going up in the next issue. It depends on the manufacturer and era, though. A lot of the classic Bally and Stern games from the late 70's and early 80's have been going up and ought to be reflected in the new price guide. Also a number of Gottlieb games from the 80's and 90's even. When I see them come up for sale, the asking prices always seem higher than what the price guide says.
