During GDC 2013, Epic Games release a rather impressive new Unreal Engine 4 trailer that shows what we can expect from future games that will be based on it and it sure looks impressive.
The new demo, called "Infiltrator, shows some impressive and stunning graphics rendered in real time. Nvidia was also quick to brag that Epic Games used a single GTX 680 GPU for it and we certainly hope that we will see more of it quite soon.
On a similar note, Epic's co-founder and Mark Rein noted that Unreal Engine 4 will not work on Nintendo Wii U. On the other hand, he did note that Unreal Engine 3 is still with us and will probably be the choice for Nintendo Wii U.
