Legend
IIRC, Mearls has commented that human characters are by far the most popular, then the "big three" of elves, dwarves, and halflings. Beyond that, the popularity drops off very significantly.
So, whether it 'should' or not, I would expect the core world to focus quite heavily on those top four races. They will almost certainly do so in an 'inclusive' way (that is, there will be space for anything a group wants to include), but those four races will get the lion's share of the attention.
As for my preference: I don't really care. I play Eberron, so I'll be looking for the appropriate races to be supported asap. Beyond that, it really doesn't make much difference to me.
