but blue rays are sony invention? what happened to microsofts hd disc? that is what you call behind the times lol. trying to beat sony, failed and now have to pay sony for every game made for the xbox as it uses copyrighted blueray tech straight from sony
as for 4k gaming neither console actually supports full 4k gaming. here is a little snippet i found regarding 4k tvs and gaming
"In comparison to a 1080p TV, a 4K set will have four times the resolution packed into the same number of inches. Upgrading will be like the transition to Retina displays on smartphones: 4K content will look beautiful, but stuff made for 1080p won’t look that much better, if at all.
Video games fall into that latter category. Games made for the PlayStation 4 and Xbox One are made for 1080p, so they’ll still look the same on the new, expensive 4K sets coming out this year.
But even if game developers for these systems wanted to make higher-resolution content for these new screens, it turns out that it likely isn’t even possible: the hardware in the newest consoles simply can’t handle outputting such detail."
