Conspiracy theorists: if you want to know why Microsoft are doing something, try asking them.
I recently saw some information on forums that seemed wrong, so I did a bit of research and found a presentation that seemed to apply. Microsoft presenters normally put their email addresses on the cover, and this was no exception, so I emailed the presenter asking him to clarify a few points. I got a nice reply back which covered what I was after.
Yes, I know that’s very wooly. I asked if I could blog the conversation and he said no. However, there should be some official information appearing later today. When it does, I’ll update (if I remember).
When in doubt, ask. If they can’t say, they’ll normally say so.
