It is very likely that I (or/and another collegue from CRM programmability) will be at Convergence 2007 this year.  If you are a CRM customer or partner with an active NDA with Microsoft, there will be a chance to test drive the all new CRM Titan developer experience and tools.  I am planning to run a number of one-on-one API, workflow and programmability usability studies, so drop me a line and book your place!  Please note that the space is very limited so you need to hurry!
