Uncharted Drakes Fortune Easter Egg - Jak and Daxter Reference

In the very first cut-scene and level if you look at the wet suits that Nathan and Elena are wearing, anyone who played the previous Naughty Dog game Jak and Daxter 1/2/3 will notice that the wetsuits say 'Ottsel' on them which is the name of the species of whatever animal Daxter is (an otter and a weasel i guess).
