I found these three developer videos for CRM 2011
it also has a link to the new SDK.
The videos do look pretty impressive and everytime I am watching a new video I just think that the development is experience is going to change quite a lot. The amount options we now and the fact that modifying forms and what we can show on forms has increased a lot. Its going to take some time for people to know what they can do and what they should put on a form. It’s definitely a big change but a big change for the good.
