Are blizzard going to redo the old races?

I'm hearing that the two new races have a lot more customization than the old ones. I'm also looking at them in the screenshots and videos/trailers etc and they look really well detailed.

That picture of the goblins next to the orcs, really shows the old races need upgrading. All of them.

I think while they're at it also, they should completely upgrade the faces of male humans, dwarves and night elves, and retouch all the models, also the short-timed-cast animation for the night elf male cannot survive, let it die, actually it should look like the blood elf male's truth be told.
