THQ has told SPOnG that the reason for the 
Saints Row 2 DLC delay is that it wants the content to be more closely tied to the 
Red Faction: Guerrilla demo.
A THQ rep told us, "This is to co-incide with the public launch of the 
Red Faction Guerrilla singleplayer demo. The 
Ultor Exposed pack includes 
Red Faction inspired content including a vehicle and outfit right out of RFG so we wanted to sync them up so gamers can enjoy both at the same time."
Earlier today 
SPOnG told you that the 
Saints Row 2 DLC, which stars porn star Tera Patrick, will now be released on April 23rd, having been pushed back from April 16th.
Red Faction: Guerrilla is an open world sci-fi shooter set 50 years after the events of the first game.
