As far as the timeline for Ultimate Warrior’s return to WWE, Triple H reportedly met with him the same day 2K Sports held a press event to announce Warrior for the WWE 2K14 video game.
As far as Vince McMahon is concerned, he met with Warrior for the first time during SummerSlam weekend in August. The two were scheduled to have a 30-minute meeting, but ended up spending several hours behind closed doors. The two worked out their issues and began working on a deal to bring Warrior in for the Hall Of Fame and WrestleMania XXX weekend. The deal was reportedly finalized in December, somewhere around Christmas.
