Blizzard has already shown off Diablo 4 gameplay from Nfkjasfas's blog

According to Wowhead's scouring of the Battle.net configuration files, it seems like the beta might not be that far out D2R ladder items. Namely, Wowhead discovered numerous references to the aforementioned "Fenris," mainly including header images for the launcher and similar items.

Blizzard has already shown off Diablo 4 gameplay, of course, so the game isn't a complete and utter unknown at this point. Still, there's been no official word on the beta itself, which makes Wowhead's discovery particularly interesting to franchise fans who may have chosen to skip over Diablo Immortal and its remarkably predatory monetization system. Having said that, it's exceedingly unlikely that Diablo 4 beta will feature any information about this release's monetization system, and that gameplay would be the key focus, instead.

Since Blizzard aims to support Diablo 4 for years to come, it seems reasonable to assume that the game would offer a variety of additional purchasing options for players that aim to stick around. Immortal has shown that Activision Blizzard isn't likely to forego an excessively convoluted list of monetizations to drive its profit margins forward, and only time will tell whether the company adopts a similar approach with its next flagship RPG.

It may be worth keeping in mind that a leading RPG build crafting website, Maxroll, recently dropped support for Diablo Immortal, signaling just how badly Blizzard had mishandled its monetization scheme buy diablo 2 resurrected items. As critical as the core RPG community might be of Immortal, the game is paying off for its developer and publisher, which is a cause of concern for Diablo 4, too.
