Hey guys, just throwing in my 2 cents.
Reading the comments I think its time to clearify some things here. I've been following Diablo news (especially D3) since...forever? There are some details you might have missed the last few weeks and days.
Diablo 3 has been moved to classic games on the Bnet site, and all the previous job postings for the new unannounced Diablo project have been removed from the site. Just one job posting popping up, for the Diablo franchise in general, with C++ knowledge, and at this point speculations have gone wild as D3 may very well be in maintenance mode for good. So a new class or even an new Expansion for D3 is very unlikely at this point. It could be, but I am not betting on it anymore, since the game got moved to classics on the site. This means, in my personal opinion, that the game is done, seasons will go with the newly announced themed seasons for as long as it takes and new content will probably be just some bugfixes and patches throughout D3's lifespan that is.
What is coming next then?
Well D4 is innevitable. A Diablo 3 Eternal Collection Port for the Nintendo Switch may be a realtity too. A mobile game in the Diabloverse is likely too.
If you look all the job postings and all the news that have been online since there was the first job posting in 2015 for an unannounced Diablo Project, you may be understanding my suggestions.
If D4 will come in the next 1-2 years, it will unite MMO elements such as Lost Ark or similar games, with Microtransactions for cosmetics, stash, pets and so on, the playstyle I believe would be very similar as that what we know today, but there will be improvs to this. (See Wolcen)
They will probably going the Road that PoE has it going maybe...
Thanks, and have a nice day.
