I'm guessing the park knew about the fate of the Beastie at the beginning of closed season when the rumour of its demise was first heard, but perhaps they assumed it'd be replaced with a new attraction, the 4D cinema. Then when that fell through they just kept Beastie as a non-option for 2011 without spending money on making it fit to operate again.
I'm curious why they'd leave it in the park though, it advertises itself as an attraction that could be available but isn't. It's a shame as it leaves the park -Britain's best themepark which prides itself on being accessible to all members of the family - without a coaster for young children. RMT, Spinball and Thirteen are all a step up really.
I'd be very surprised if the parkwide maintenance we all want does happen, although they should have a fair bit of spare cash handy. Or an epic Black Hole replacement for 2012 I hope!
