If you have seen the site, I created a small Google Gadget to help guide your links.

Obviously, the big deal is the eight new game boards. We were careful to make certain that they were backwards compatible with the older boards so that players could mix and match. Other changes are all focused on making it easier for players to easily see their status and next steps. There are factory floor guides similar to what was in the original and 4 player reference cards. I think the biggest improvement, though, are the track guides. There are multiple suggested set ups included within this version so that gamers can focus on their strategy rather that board design. We've found that sometimes, especially when you are fairly new to the game, that without some guidance the tracks that people designed weren't necessarily the most fun. That doesn't mean that experienced players can't design and program new play patterns; we just thought that we would start you out with some of our favorites.
