Apple announced the new MacBook Air right at the start of todays special event. Included in the new Apple MacBook Air 2018 is a Retina screen and a new processor. Also, Apple updated the design of this very successful device today for the first time in years.

I doubt new Macbook Air has i5-8200Y chip. This chip has UHD615 graphics not advertised by Apple UHD617 and does not support 2333Mhz memory. It is rather not officially declared by intel i5-8210Y chip.
