An Android TV dev- kit powered by NVIDIA's Tegra K1 SoC has been shipping out to developers. The device is running a preview version of Android L and it includes a gamepad in the box. The developer kit does not include a video input, but future versions will. Android TV will come in other form factors and in some cases will come built into a TV (already confirmed for Sharp, Philips and Sony in their 2015 line-up).
NVIDIA's Tegra K1 offers performance that rivals (if not exceeds) that of the Playstation 3 and Xbox 360. It also offers support for API's such as OpenGL ES 3.1, OpenGL 4.4, and DirectX 12.
Google is leaving behind Dalvik and making the move to a new runtime, ART. Android L will support 32 or 64 bit (ARM, x86, or MIPS), and a new range of API's, including what Google calls the Android Extension Pack. The AEP will complement OpenGL ES 3.1 and allow for new features such as tessellation.
A tech demo of Epic's Unreal Engine 4 was running on this development kit at Google I/O:
At the start of this year we saw early versions of full PC ports, Trine 2 and Serious Sam 3 (utilizing OpenGL 4.x at settings higher than on Xbox 360), running on Tegra K1. With the new hardware and API support, developers will be able to port their titles to Tegra K1 with little effort.
Razer has also announced an Android TV micro console that will launch to consumers Fall 2014. No word on pricing or internal hardware, but a Tegra K1 SoC will likely be used.
