Sompeetalay from TK-421 points out quite a few databank updates on the Official Site:

The Star Wars galaxy brims with life of all shapes and sizes. A diverse array of alien beings mill about in crowded port cities, and the wilderness echoes with the cries of exotic creatures. Even in the very depths of space are life forms that can survive harsh vacuum and thrive in the airless void. Here's a sampling of aliens and creatures, added to the ever-growing starwars.com databank.

There are also 3 Quarren officials confirmed: Senator Tundra Dowmeia and his aides Zil Topur and Nor Wedd. There are new pictures of a Weequay, Quarren, Aqualish and a Sullustan. Two Rodian characters are also confirmed, Senator Onoconda Farr and Palpatine's Aide Dar Wac. Scurri?rs are also confirmed to re-appear in Episode II.
