It's terribly likely. They've been trying to work something out with the city for the past few years. The crash of the economy put everything on hold for a while, but now, it looks like the days are numbered.
But sad news for the park.. and it's a shame the Niners can't find another place to avoid all this trouble. The park is dieing slowly and unless the Niners want to invest in the park.. I doubt it will survive at this rate.
Niners need a new park, and they set their sights there and won't move it. If it was a bigger park, this would have never been a question, but were looking at a meh park, and a football team trying to get back to its glory days, and it would let them eventually host a Super Bowl (probably) as I believe the new stadium designs call for a retractable roof. Sad, but not worth crying over.
To be honest I really like the park; it was pleasant enough and the rides were ok, Flight Deck being very good. Though it wasn't too busy and is obviously not getting the turnover it requires. Hope it manages to keep going.
