I think this reflects my idea of what the community will think. They did a good job of making the Demon Hunter badass, so even though the archetype isn't as popular, lots of people will play it just because it looks so cool.
Personally, I can't decide between Monk and Barbarian for my first class. Every time I think I've decided on one, I find out something cool about the other. Demon Hunter comes in third for me, followed by Wizard and then WD. WD is the only class in the beta that I didn't really have any fun playing. That being said, he gave me the impression that the class will be RIDICULOUSLY powerful at higher levels. Just not for me.
Therefore, I think WD will become much more popular when people realize he "owns" and perhaps numbers will even out.
I cant believe that people think WD is least playable. WD is the only class that has a little bit of every class and plus more. Playing a WD is just as effective as playing other classes even without minions. YOu can focus on Direct dmg, AoE dmg, CC, minions, or on all mentioned. The most fun class to play, and it greatly scales with levels and gear.
