In the same way it has teased us about upcoming DSLR announcements, Canon Netherlands has posted a video that hints at an upcoming PowerShot zoom announcement ("grote" means "large" in Dutch). You can find the page that contains the video here (scroll down near the bottom of the page).
In my opinion, this type of marketing was certainly appropriate for big-time DSLR announcements – but teasing a PowerShot zoom seems to be a little over-the-top for me.
