Xbox One/PS4 is when both sides standardized on BluRay.

When Xbox360 and PS3 came out, the format war was only just starting, and the consoles were on either side of it.

PS3 came with a BluRay drive and the games were delivered on BluRay.

Xbox360 came with software support for HDDVD, but the actual disk reader hardware was a DVD reader (famously, a large off-the-shelf part selected at the last minute that required a redesign of the cooling system to accomodate its size), and the HDDVD drive was an optional add-on that nobody bought.

The fact that every PS3 could read BluRay, but you needed a special extra to play HDDVD on Xbox 360 is arguably the main reason BluRay won the format war.

Which is probably why Microsoft decided to focus so much on media features for the Xbone. What they should have considered was that they had won the Xbox 360 generation by being a better game platform; it should really be no skin off Microsoft’s back that Blu-Ray won the format war.
