it tries to streamline some things as far as I could tell. For example when you click bevel the actual number input areas kinda follows your mouse instead of appearing near the bevel icon. it was odd and I really didn't check it out too fully 'cause it was during a competition but it was very similar to 09 as far as I could tell. really didn't go in depth such as mental ray materials, dope sheet, and I didn't see or try all the object mods.
