An update to the character creation for the existing playable races should be a priority for 5.0. I do not want to see any new playable races added to the game until we get a wider variety of options for what exists already.

We get new hairstyles with each major content patch and also with the occasional seasonal event. That's pretty great - but we should be getting other things such as new facial hair options for men and make up options for women. Many NPC's now have unique facial features that look brilliant - but we risk seeing the same problem as with in WoW where major NPC's end up looking a lot better than player characters. Hopefully it's something that is on their radar now and will be addressed in the future.
