voice

I understand that LTE and WiMAX are IP-based technologies that do NOT have a voice component unlike the current 3G technologies. So is it like, voice calls in 4G would be completely driven on top of IP? Wouldn't this break backward compatibility with existing 3G technologies? Is this why 4G is taking it took long to take ubiquitous availability?
