According to an article on engadget mobile, details confirming previous rumours of the HTC Hero were leaked by HTC’s own website.

The HTC Hero features the new HTC Sense widget based interface that places info up front on the HTC Hero home screen. Also a new Scenes profile allows the user to transform the handsets focus from business to weekend mode.

This was of course before HTC officially unveiled the HTC Hero, but it is somewhat strange that you could get the above info from the HTC website before the official launch event.
