Both are bang up to date, including Sketchflow and Blend 3 for designers and RIA Services, PRISM and M-V-VM for developers.

Take a look:

• Silverlight for Designers with Blend 3
• Silverlight for Developers (inc Ria Services, M-V-VM and PRISM)

bbits courses can be customised at no extra cost, so if you can’t take the 5 days for the full developers course, you can cherry pick the bits you want and just do them!

Cheers
