So on Friday Greg and Ion had an interview with Gamebreaker.
Interview can be found here.
If you skip ahead to 15:55 and listen you will notice that Ion does leak the release for Tuesday and saying I quote.
"I am sure we will see them in this coming week running in there with raid of half main half alts"
Huge leak on his part he does studder, so I think he got the go ahead to say it I am surprised that the interviewees didn't pick up on it and ask immediately after.
So I guess we should all prepare for patch Tuesday.
