Nexus Player - Apps, games, and more for your TV

So essentially a Google game console/Android TV. Interesting. I wonder if this means more graphics intensive games like GTA V or Destiny will show up in Google Play when more powerful Android TV devices arrive. The video game console space may be very crowded in the near future.

I'm a long time Roku and Chromecast user. I wonder if this will be able to replace both in one swoop.

Why doesn't it have an ethernet port? I mean it's great to see that finally more and more people are jumping on the MIMO wireless train to allow direct inter device communication, but the more devices we have the more crowded are our wifi networks at home. Especially with stationary devices like the TV at home providing a cable doesn't hurt and only brings advantages.
