Oh I'm sure he has an idea. He just doesn't care.
And people here or on social will go to bat for him saying he's doing his "job". Many journalists have access to the same type of info and don't go spouting it, but Grubb's created a persona and platform off it and will milk the clout until it runs out.
A leak like this really benefits no one but Grubb (and I guess w/e's left of GB now). He's not divulging some fucked up industry thing that needs fixing or sharing important info that's helpful to anyone. It's totally self serving at the expense of real people that work on it.
Yep this is pretty much it. If he had any sense of self-awareness then "There's a AAA Black Panther game in development" would have been just enough without the extra vague info causing so much speculation and toxicity.
What makes this more frustrating is that the way he goes about it really drives your points home.
I'm not sure if it's been mentioned in the thread yet but Friday during Kinda Funny Games Daily, Grubb was in their Twitch chat jokingly teasing this story to them like, "Well, I guess I won't tell you guys about the Black Panther game I just found out about!"
It's just weird and unprofessional for something that is so early, with details that aren't finalized at all.
