The post is misleading. This has absolutely nothing to do with cassettes and the Walkman never went away having evolved to CDs, DAT, MiniDisc and their first DAP ("mp3" player) in 1999.

This is just the newest DAP model of Walkman targeting audiophiles. It runs Android and can download or stream over WiFi. Its specs are impressive if you're into that sort of thing. It's like the restaurant in The Menu only its audio instead of food, but probably attracts the same cast of characters. For almost everyone else, phones are the way to go.
