Question about Windows Mobile 7

[Curiosity]

I know that those who know WM7 (Photon) are under an NDA, but I was wondering if those who know might know if WM7 will have backwards compatibility with programs running on WM5/6. I have AT&T Wireless and I'm scheduled for a phone upgrade later this year. With HTC TyTN II's video driver issue, I thought I would wait to see if something will come out that will suit my wants. That wait may push me back to next year and since WM7 is thought to be pushed back to Q1 2009, I might be purchasing a WM7 device. For those who know, if it doesn't violate the NDA, would you be willing to shed light on this question?
