The upcoming X-Box Series X

Yes, I currently own an X Box One X

When does the new X Box series X release this year?

Will it have blue-ray?

I have a 65 inch, 4K television.

Will I see a difference in graphics with the new X Box on my 4K?

Xbox Series X will release Holiday 2020, given Xbox's track record of releasing new consoles, they've usually been around November.

It will have Blu-Ray.

With the Xbox One X, it uses checkerboarding to get 4K resolution, though it's not true 4K, it's what allows the One X to get to 4K,

With the Xbox Series X, it will use true native 4K, you may see that the Series X will look a little better at 4K than the One X at 4K.

I think it will release around Christmas time this year.

The Xbox One X console is made to exploit all its capabilities on your screen, I recommend playing 60fps

Going out for 2020 vacation
Yes, it will have a blu ray reader
Apparently it will have ray tracing, and better quality in games so in part if

Not only will you see the difference on your screen, you will definitely notice the fast and responsive load times of games, as it has a highly optimised Solid State drive which will be truly amazing! You can not go wrong with this next gen for sure!
