A little late in the day, but Nvidia also announced a Shield console that's also a 4K Android TV. The new Shield will only cost $199 (about £180, AU $255) and will come bundled with a controller.
We thought virtual reality was huge last year but it's even bigger this year.
The new Morpheus packs an 1920 x RGB x 1080 OLED display with an impressive 120Hz refresh rate. The prototype has a 5.7-inch screen with a 100 degree field of view.
Even better, Sony's Shuhei Yoshida confirmed that Project Morpheus will launch to consumers in the "first half of 2016".
It's not Half-Life 3. Or the HTC Vive. But Valve is releasing a device called Steam Link, a $50 (about £32, $64) streaming box that will let you broadcast games from the PC to the TV. That will support 1080p at 60Hz with low latency.
Valve also confirmed the final specs of its Steam Controller, which we'll be grabbing hands on with later this week. The Controller will have both touch (haptic pads still in place, then) and motion capabilities.
Beginning today, an alpha version of the development kit will be available to help devs make VR experiences better with AMD hardware.
AMD says LiquidVR lets developers make virtual reality with less latency and better comfort and performance, as well as plug-and-play capabilities for a variety of VR headsets. The company has partnered with Oculus Rift and other "key VR developers" to further improve its initiative.
Unity Technologies, the popular company known for its multi-platform engine and development tool, announced Unity 5. Available immediately, the engine is touted as the most powerful, next-gen Unity to date.
Huge improvements have been to graphics and an expanded editor feature set gives developers the potential to create gaming experiences across 21 platforms.
Unity Cloud Build has also been released to allow cloud computing which will "increase productivity" to devs can focus on the creation of games.
Steam Machines haven't disappeared. They've just been ... scarce. That will hopefully change this week.
Syber, a division of CyberPowerPC, has unveiled not one or two but a whopping six machines including the: Steam Machine-Mini, Steam Machine-Mercury and Steam Machine-Switch, as well as the Steam Machine-P, Steam Machine-K and Steam Machine-X.
