Computing capacity. That is still the basis for 'the next leap'. You ain't seen nothing yet. Moore's law is by no means finished and processing power will make a lot of mind boggling new things possible.
We're already entering that era with things like cell phones and GPS devices. You've already seen this era being born. So I sort of vagually agree with PolymerTim and bwanaaa, even if I may not exactly agree to their scenarios in detail

Just one example of 'magic' things maybe emerging could be a new sort of view technology, synthetic view point space (or view space) and synthetic view angle. This as usually immediately has some military applications (most immediately for UAV piloting) but would also maybe be interesting for the entertainment industry. Just a brief description of what this would be: Imaging from a camera is not just simply displayed. Instead it's continually collected to build a 3D or 4D data representation of what it 'sees'. Parts not visible are remembered or guessed. As information continues to be collected by the camera the representation will be increasingly resolved. And it doesn't has to be just one camera. It can be many cameras connected by a network. And instead of viewing the scene through the camera from the camera's momentary position, a viewer can freely choose the viewpoint in a 3D space. The displayed image will of course be synthesized.
So instead of showing your friends and relatives pictures or videos from your vacation, you may instead take them on a virtual trip in a 3D world, even with stereo vision. Take them anywhere they want to go, as long as your cameras were there.
And that's just an example. I don't think we're able to imagine the things that will be possible.
As for wireless power, it's physically possible but by its very nature it is also dangerous, too dangerous. It's also inefficient and 'dirty' which goes completely against the demands of energy crisis and 'green' needs. So no. Absolutely not. Won't happen. Only wireless power you'll get is solar power.
