This is a deal that RVD and Triple H came up with, one that was signed off on by Vince McMahon. One of the reasons for the deal is RVD has so many of his own projects going on. RVD and WWE are on good terms with a new action figure coming out soon and a possible DVD in the future.
While RVD is away from WWE, he can still work for other wrestling companies but cannot appear on any of their TV programs. Word now is that he may be gone until the Royal Rumble season. WWE creative wants him to return then and work from the Royal Rumble through Extreme Rules, which obviously is more than 90 days.
