This is going to be a work-in-progress thread for some of my Unreal Engine 4 experimentation. It'll probably start off with reference links and concept art or ideas and go from there.
Unreal Engine 4 is now a $20/month "software-as-a-service" license, and yes, that includes source code. The only things locked down to individually negotiated licenses right now are the PS4/Xbox One integration source-code (& Epic is working with their lawyers on some-how including that).
This is hugely exciting for me, as a Unreal3 + L3DT user, due to many of the core engine improvements (such as a totally reorganized real-time lighting model, etc).
Here's a link to the Landscape stuff for Unreal 4 to start the thread off.
