Beyond Calibri: Finding Microsoft's next default font (microsoft.com)

…do they show the fonts anywhere? Is it just the images with a few random letters scattered about?

why they dont provide the sample how the fonts looks?

Even every link on page didn't have preview of fonts.

The fonts can be found here (link near the end of page): http://aka.ms/officefonts

Caveat (from the page):

"Cloud fonts are only available to Microsoft 365 subscribers. Documents that have cloud fonts will render correctly in Office 2019."

Examples of the fonts here:

I guess it's always nice to have more source typefaces but until Microsoft addresses the downstream pixel chain of the platform, the typical user's experience will still be a mess due to inconsistent HiDPI scaling and other issues.
