This morning at the first session at the MVP summit Scott Guthrie is addressing us. I asked him if there would be additional content beyond what they are telling us here. He promised that there would be many new announcements at MIX and that it would be worth our time to go.
The early bird discount for MIX ends at midnight tonight so you need to sign up early. Or.... if you are a good designer (not the gray background and square buttons type of design that I do) you could enter the REMIX contest and design your way to MIX.
At the conference you can get information about Expressions, "WPF/E", and other design tools. If that is enough you can sign up to get into the MEDC (Mobile and Embedded DevCon) at the same time.
All attendees to MIX will get a copy of Windows Vista Ultimate and the right to purchase two additional copies of Vista Home Premium through the Windows Vista Family Discount so not only do you get a lot of good information but you also get some cool software.
So don't delay. Go register at visitmix.com. I will be there and joining in the conversation. After what I am seeing here I am excited for the announcements that will come out at MIX.
