Is this an out-of-season April's Fool joke?

[TheLegoMaster]

He’s not even smiling when he says that. He’s dead serious.

[theeverchosen]

When someone heckles you at your own event... and the crowd cheers, thats a bad sign

[ginyutiki]

"Good work Agent 47, Blizzard's reputation has been eliminated. The money is being wired to your account, now head towards an exit"

[ivancerecer]

"Welcoming our community back to it"

Ah yes, a community of hardcore pc players would surely love playing on a phone

[nyx]

He went to Blizzcon as a fanboy, and left as a hero :p

[florianfrueh]

not even diablo himself could burn somebody that badly....respect.

[jacobcore]

Literally the first frame is like a work of art. The single spotlight on him. Dressed like the rest: a man of the people. He relays his message; one of pure disdain. Absolute kino

[TheTSense]

He gave Blizzard their last chance. All the planning, all the testers, they had all failed to stop this ruin of a move.
This was the golden ticket, the last way out. The last train leaving before midnight, the last escape pod on a burning spacestation.

They just had to say yes.

This has more likes than the actual game trailer.

[DolusVulpes]

Considering that Diablo Immortal has been listed as "coming soon" on the Google Play store for the entire 2 years since this video and still is today, I'd be willing to say that yes, it was an out of season April fools joke.
Edit 1 year later: It wasn't, bit I really wish it had been.

[afkftw]

Turns out the whole company was an out-of-season April Fools Joke.

[Voltroc]

And now that we know it's going to take over $100k to fully gear up a character, I would have to say that yes, yes this game is a massive joke.

[Tailstraw_xD]

After this, Blizz made a policy of not taking questions or comments from people in red shirts at Blizzcon

[_Ikelos]

You have to see this in the context of a guy loving Blizzard so much that he bought a $200 ticket, then travelled all the way to Anaheim, rented a hotel room and waited outside the convention center to get in and actually got to sit down at the Diablo panel.
*That absolute fanboy* was pissed off, disappointed and disheartened enough to get up there and say that.

Blizzard has been pumping out sewage waste for years now, and the fanboys (me included) kept buying with the hope of shit getting better eventually.
They had such a fanatic core audience that they could do almost no wrong as long as it looked good, and they managed to burn all of that down.
A gold egg goose securely in their possession, and they just strangled it with no remorse.
It's no wonder every other dev worth anything walked out.

[Mordhyrr]

The only part of the whole panel that was worth while watching

[mrpineapple]

"dOn'T u GuYs hAvE phOnEs???!!?!?!"
I'll never forget it

[ReasonTermination]

With the release of the game, and how much of a cash grab pay to win shitfest it is,

This guy was ahead of his time.

[Jupex]

They are so excited about the game that they outsourced its development to China.

[nepozepo]

There is something so tragic yet so funny about watching a game be announced, recieving one of the most lukewarm crowd reactions ive ever seen, then opening up to questions only for the first question to be basically-"wtf is this?"

[Wtahc]

"which everyone will get to play"

"Will this be available on PC?"

"No"
