"Jurassic Park" Sequel Out Within Two Years?

"Jurassic Park" producer Frank Marshall was asked again about when the fourth film will come out. He  answered by saying that the film could be hitting cinema's by the year 2014, "I would say that it will be on the screen within two years".
Next year will mark the 20th anniversary of the first "Jurassic Park" film, so I could see a new sequel coming very soon.
