Hm. The only question about this seems to me if this means there will be an updated box or no box anymore.
Isn't Cortex for PC something completely different?
So many games, so little time...
Think of it this way, if Google was to make an Android TV version of Chrome that have all the requirements to be considered optimized for Android TV at the same standards they put on any other app while at the same time functioning well at displaying and controlling any website then what would be the point of having Android TV apps for Netflix, Hulu, YouTube, Twitch, Vudu, Showtime, Pandora, etc.? If the answer is that there would be no point then devs would have no reason to optimize apps for Android TV. If the answer is that there would still be a point because the apps would be more optimized for TV than using them on Chrome then that would mean that Google was unsuccessful at optimizing Chrome for Android TV in the first place because it wouldn't be able to display these sites in the same optimized way as they would as separate Android TV web apps.
So, it makes absolutely no sense for Google to make an Android TV version of Chrome.
Now if you want to argue that Google isn't doing a good enough job on making the Android TV version of Google Play have more and better categories, every game/app for it easily discoverable, have no need to do voice searches for hidden games/apps that you can't find in the categories, etc. then I think you would be making a good point about them poorly supporting Android TV because Google Play on it is horrible. That argument would make sense to me because that is the store for the platform. But no Android TV version of Chrome? That argument makes no sense to me. Android TV is meant for consuming media and games on a TV. It isn't meant to be a Chromebook.
