Look for me on the local news, I'll be the guy arrested for trying to burn down a Nintendo exec's house.
The very fact MS wanted to keep this non-total public knowledge for the dumb show oomph just goes to show why both Sony and Nintendo are ahead of them with regards to indies. When the info is available on such matters, push it out so that people can target your system as soon as possible! Don't keep it secret for months and then get mad you don't get your big "LOOK LOOK WE'RE MATCHING THOSE OTHER GUYS AND ALSO THIS DEVKIT ACTIVATOR!" moment like a brat.
