Actually video conferencing fills a real need. People like being able to look at each other when they talk (we get a lot out of nonverbal communication).
On current mobile networks you just can't do that though (that's why facetime is wifi only, I gather). Not to mention that it will still drain your battery pretty damn fast. You make it sound like it's really easy to do right now, while the conditions haven't even yet arrived.
3D displays on phones seems fairly implausible. An extra camera will take space, and why would we want to use that much extra resources just to see our buddy's face in 3D? Now if they had said "in 4 years time, we will have video calling generally available on phones", that sounds pretty damn plausible.
