I doubt the sequel will be delayed. Singer and crew have been acting like the sequel is next after Valkyrie, so I'll take their word for it over some producer's. In the end, Singer is going to have to come down to a decision--either Superman or Castro Street. And considering Warner Bros. isn't going to let anyone screw with their franchises, he's going to have to choose Superman.

When you see Jerusalem being surrounded by armies, you will know that its desolation is near. Then let those who are in Judea flee to the mountains, let those in the country not enter the city. For this is the time of punishment in fullfillment of all that has been written. How dreadful it will be in those days for pregnant women and nursing mothers! There will be great distress in the land and wrath against this people. They will fall by the sword and be taken as prisoners to all nations. Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled.
...At that time they will see the Son of Man coming in a cloud with power and great glory. When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.
Luke 21:20-28
