I haven't a clue what Canada's Wonderland is announcing in 20 or so days, but I'm now more anxious than ever with new teasers going up on the park's website. They have a page with a countdown to the announcement, and their main page also features a stormy graphic/explosion type thing going on. The slogan "prepare to be blown away" leads me to think that it could be a launched ride, but also that it could be themed to some kind of storm or weather event.
The footer work has continued at a rapid pace - there's now numerous ones poured with plenty more on the way. Can't wait to see what it is!
