There is a review of the DAoC expansion Shrouded Isles over on ReviewOutpost.com.Out of a possible 100% SI received a grade of 93%. Here's a snippet from the review you can read the rest here:

Shrouded Isles is definitely a great addition to Dark Age of Camelot. Mythic has done a great job at keeping things balanced, new and exciting for its players. The graphics are amazing. My only caution would be to look out for major lag if you do not have a decent graphics card and connection speed. The mystery, the chaos, the danger and the overall excitement are a delight to the roll players senses. Three new islands to explore, new classes, races, and beautiful visual effects. All in all I was consumed by all the new features Shrouded Isles offers.
