Just had the details of WES 2006 sent to me. Contrary to what was said before about Dallas it is now confirmed as Florida again and the date has moved back to may as per previous years.
May 16th - 18th
Go here to register for updates. It's on the old wes 2005 page, with 2006 updates, and when you fill it out it thanks you for registering for updates on wes2004. Interesting! https://www.rim.com/symposium_contact/contactAdd.jsp
