Well looks like the HTC HD2 (Aka Leo) has been let out of the bag. The offending company is Orange UK. They appear to have dropped catalogs listing the device early. So far the launch date has been set in October. The actual day has been listed as the 12th and the 26th. No one really knows which one.
It is also speculated that Orange might have dropped this little teaser to gain back some business they are going to lose now that they are no longer an exclusive provider of the iPhone.
An e-mail to HTC's US PR firm did not gain any information other than HTC is making an announcement sometime next week. Again this is not a lot to go on but enough to keep the HTC fans eager for more.
