For the hyper rumor, I might be able to get some information on it because my friends claims that his mom has a friend that works with BGA and has supposedly said something about a new coaster (specifically 'hyper' type) and will be coming in the 2009-2011 years. I will try to get more information.
^ I agree. BGA is getting Jungala, which is a big addition, but I don't think it is a good idea to retheme Timbuktu. Hopefully they will do something better for their 50th anniversary, and a B&M hyper would be nice.
