It looks like PDC10 will have an interesting twist, compared to previous PDCs:
I also didn’t see anything about a schedule, so I don’t know if there will be pre-conference sessions this year. The site does say that the focus is going to be on “Cloud Services, Phone, Tools & Technologies, Internet Explorer and Gaming”. I’ll provide more information once I learn more about it. Make sure you keep an eye on http://microsoftpdc.com for more information as well!
