What countries currently support 4G LTE? - Quora
Only the red countries accorinding to that map currently have a live LTE network. LTE is obviously a big deal for those who have access to it but given the iPad is a global product, there are many people for whom LTE will not have any impact on their iPad purchasing decision.
If their management saw potential in fast growing LTE, than I am sure iPad 3 will be LTE supported. If they dont see potential, than iPad 4 is reserved for LTE.
Be aware that Apple built his highly respected image in tech. world because he is one that brings fresh technology to customers, that others just cant in that moment.
Apple has to jump into LTE at some point. They build products to last more than one year, so even if LTE may not be a big thing now, they may be more likely to add it to the iPad 3 because of taking care of customers future needs. Think of how few places had 3G when the original iPad came out. Their biggest concern is going to be battery life. I would think that the LTE chip will be designed to not draw power unless it sees a network, and it could be turned off when not wanted.
Current LTE chipsets are dumb and high power. Until the low power chipsets are available in quantity - estimates are still a year away - Apple will not support LTE.

Sure, some consumers might want LTE now, but I'd venture to say that many don't want to give up battery life to gain speed. What is the use of a mobile device that quickly needs recharging?
Do not forget that the high battery drain is only when operating on a 4G network. A lot of people may want the ability to use the service, but will rarely connect. Software can be used to keep LTE off line unless the 3G is slow due to high usage. Or there could be a selector system to choose performance level vs battery life.
