Finally it comes.. VISIO 2010 is going to come with the BPMN support. Can't wait to try my hands on it. The biggest thing last time(Visio 2007) was the support for cool data visualizations. They seemed to have waited too long to get onto the BPMN league. But here they come. Take a look at some of the screen-shots from the MS site. I hope to get a copy today. There will be more on it soon.
