Is tiled forward rendering the new hot thing?

I see more and more people talking about tiled forward rendering, and it seems to be the new hot thing everyone wants to try. AMD recently released a tech demo using such a technique: Leo.

Aras Pranckevičius, rendering architect at Unity, discussed modern forward rendering in an article, 2012 Theory for Forward Rendering, and later dropped a bunch of Tiled Forward Shading Links (which I won’t duplicate here so just click). Wolfgang Engel argues tiled based approaches don’t pay back when many lights cast shadows, compared to deferred lighting. At last Brian Keris discusses Tiled Light Culling, for the diffuse and specular contributions.
