Sorry for the lack of updates, but we've been pretty busy. On what, you may ask? Our PM, David Teitlebaum, just did a video on Channel 9 showing off the new features. He starts by covering interactive 2D on 3D and improved layered window support, both of which were in 3.5, and he finishes with the customizable ImageEffects, the much improved WriteableBitmap, BitmapScalingMode.NearestNeighbor, and D3DImage.
