EDIT: Also i remember reading a while back when Lich King was announced that they had Certain ammount of people working with WoW Stuff, another amount on Starcraft 2 stuff and another amount on UNamed top secret game(i forget the numbers)
It appears this is a convo with an unarmed Blizzard rep whom Mats used a bit of social engineering on to spill the beans...
I think for the time being this can be categorized as hearsay and is not refutable until investigated further perhaps by MD. Also, I cannot determine when this convo took place although it is dated May 5th 2008. Perhaps Mats himself can shed a little more light on this...
Blizzard-producer: How do you like Irvine then?
Mats Nylund: Sure, its the second time Im here in about a month. And I'll probably be back soon to check out Diablo 3.
Blizzard-producer (as if it were implied that i know everything about diablo 3) : Yeah, well im not really sure when that event is...
Mats Nylund: !!!
You heard it here first, kids. My guess is advertising at E3 or World Wide Invitational. Or perhaps Games Convention?
Better translation ,also i asked a person who lives in sweden , it seems legit.
Edit : this guy is on the staff page of the magazine
2nd Edit : In the comments someone said; OMG! But does this really mean anything? Perhaps he was just messing with you?
and mats answers; Not impossible, but it seemed so self-evident to him that there was a Diablo 3-event coming up around fall/autumn, så i think it was a real slip of the tongue (mat is the guy who did the interview )
Am I the only one that doesn't see much in that blog.
In my view : ''Yeah, well im not really sure when that event is...'' could easily just mean: '' jeez haven't thought about Diablo in 5 years.....''
