I was at SFoG Sept. 30 and the Viper land is dramatically different. Both spikes are gone AND the loop is gone. The only thing that remains is the station and a little bit of track on both sides of it. The grassy hill on the exit ramp side of the station is now a large "construction-like" dirt hill with a crane there. I didn't see any new track pieces, but SFoG is obviously in a hurry for something. I wouldn't be surprised if even more changes occur to the area before the park closes.
As for it's new location, I've heard SFA and VisionLand (a good park for it) mentioned.
