That sounds silly though, the number off 4K panels out is tiny, people don't upgrade TVs often. So they are just limiting who can even want too buy the console. I guess its console gaming and you can't decided how you want too game.
A study on the net reckons 35% of US households and 25% of EU households will be 4K by 2019 whereas it was only 1% in 2014. Prices are falling all the time. My dad paid the same price for his 4K TV (cheap Chinese thing) as I did for my Sony 1080p TV and I'd say there wasn't much difference in visual quality when playing video games. (The TV picture was a different matter though.)
