I've heard it was for 2011, but later than '11 would seem more sensible, because as you mention, new islands. Look at Saw, it was 2007 the land for it was infilled, then it was left for a year and a bit before work started on Saw itself. It's gotta give itself time to adjust, just like the land along Colossus' loops is doing this year, ready for next year. If they infill some land for a new coaster in 2010, the the chances are construction will be in 2011, ready for 2012. You're idea gives me an idea. Alton have got Extraordinary Golf based on their rides - Thorpe should do one too!
