Notice also that the new LTE-enabled iPad doesn’t sacrifice
battery life compared to its 3G predecessor.
Between generation 2 and 3, the iPad battery increased in capacity from 25 watt-hours to 42.5, a 60% increase.
It's a safe generalization to describe the iPad as "a large battery with a thin layer of electronics wrapped around it": http://www.ifixit.com/Teardown/iPad-3-4G-Teardown/8277/3 http://www.ifixit.com/Teardown/iPad-3-4G-Teardown/8277/3

My bet is that the wifi model doesn't get much better battery life than the LTE model, at least not 60% more. A good reason for that increase in battery capacity is likely needed for the video upgrades, both the screen and the quad-core graphics. A better comparison would be a LTE model running on LTE and then a similar comparison of the same model running on 3G instead. This would tell you what the difference in the two would really be like. My guess, it's probably not insignificant, but it probably isn't as bad as we see on Android phones.
