Please...Apple, Amazon, etc.
You don't know anything about gaming.
You sound like Palm and Blackberry executives did when the iPhone was rumoured/released.
Android and iOS have already hurt traditional handheld gaming (Vita/DS lines), slide 7 of this IDC and App Annie report sums up just how big they've gotten: https://s3.amazonaws.com/files.appannie.com/reports/AA-IDC+M&P+Gaming+Spotlight+4Q14.pdf
You sound like a gamer. That's fine, PS4/XB1 aren't going away.
But people like me who game casually - I'm excited to see what can be developed on the Apple TV. And as the Wii showed and iOS/Android gaming shows - there's a huge market to tap into. Those of us that don't want to spend $300+ on the console, and then $30+ for the top games.
Real Racing 3 came out over 2 years ago (for free) when the flagship iOS devices were the iPhone 5 (with an A6 Soc) and iPad 2 (A5). For it's time it looked and played decent. I'd love to see what a new Real Racing 4 could do on an A9X found in the iPad Pro:

Just look at how much more devs have to work with now compared to the iPad 2 when Real Racing 3 came out.
And then think about an Apple TV with an A10X in a couple of years that supports true 4k and hopefully by then there are decent MFi controllers (or even a good 1st party controller). This is another reason I think this generation has been capped at 1080p, video playback at 4k is one thing, developing smooth apps (particularly games) at 4k is another kettle of fish.
So in 2017/8 there's potential for a 4K Apple TV versus the PS4 and XB1 that can only do 1080p. My outlandish prediction? I think we will see new consoles from Sony and Microsoft way quicker than we have over that last few console generations.
Like I say, I'm excited to see where this goes.
