After seeing the latest spotlight on the gnome, I'm betting it's pretty safe to assume that all the other races detailed in Urban Arcana represent the revised races (sans the translational feats).
1. A Dwarf's base speed of 20 ft. remains the same even while carrying a medium or heavy load.
(I like this one )
2. Half-Elves receive a +2 species bonus to Diplomacy and Gather Information checks.
(Yeah, that'll make me want to play a half-elf.
)
3. Halflings gain a +1 species bonus to attack rolls with thrown weapons and slings.
(I still say a sling is a thrown weapon )
They don't account for things like weapon familiarity, but I think we'll see the above changes in D&D.
