TomTom has called a Media Event for September 22nd for some journalists (apparently yours truly wasn't on the invite list). They aren't sure if this is for the iPhone app and holster (which had UK pricing of £113 leaked a few days ago or something else), but the message is about how "TomTom will reveal the future of navigation to you".

Also, this is from a .nl site via google translate, blogged by a rumors site, picked up from an iphone subsite of the "topnewsdigest" site, and then by me, so take it as worth the paper it's written on :)
