I personally think this is really great! The Little Dipper is one of the few things I remember going on at Kiddieland when I was a kid. It will be perfect at SFGA, but I am wondering too.
This should also give a pretty good indication that SFGA is not concerned about closing down anytime soon. I doubt that they would, but this pretty much makes it for me that they are seriously staying open if they can spend the money to get a wooden roller coaster which they probably have to take down, transport, and rebuild at Great America due to the pretty large distance between the two parks.
I also like that Great America, over the past five years, has really started to become a bit of Roller Coaster Collectors and are trying to keep the Classics still around.
In regards to the Little Dipper, great addition! A family wooden roller coaster that is decient on the Thrill Factor.
