Thank you for contacting us.
Regarding your questions I'd like to say:
1.) If you choose to upgrade to our bundle (RadControls for ASP.NET AJAX + WinForms + Reporting) until October 1st, 2008 you will receive our RadControls for WPF and RadControls for Silverlight at no additional cost. All products included in the bundle are offered with Developer license + Subscription.This means that you will be entitled to receive all version updates (major and minor) for the included products for a period of 1 year. As part of this license you will be also entitled to a Gold Support Package which guarantees response within 24 hours.
2.) To answer your second question, currently it is not decided yet if an option for an upgrade from RadControls for WinForms to RadControls for WPF will be offered. Most probably you will need to buy a new license for the WPF controls in case you prefer to wait until the official release of WPF controls.
My advice for you would be to choose the option A and upgrade your WinForms license to our bundle. This way you will not only continue receiving latest versions of the RadControls for WinForms, but also you will receive our RadControls for ASP.NET AJAX, Reporting, Silverlight and WPF.
Please let me know if you have any additional questions or concerns.
