Epic has released info on Unreal engine 4.
Square Enix has release a tech demo called Agni's Philosophy as well as posted job openings for next-gen game engine development.
I'm curious what your thoughts are on the two. I'm blown away as always with the textures and animation in most everything Enix does. Epic on the other hand is doing fantastic things with lighting and color. That's pretty funny considering how brown, dull, and dark their games are, but progress is awesome.
What are your thoughts on this E3's engine/graphics developments?
