Up on MSDN, the The North Face In-Store Explorer White Paper and Sample has been posted, updated for the February CTP. A couple things to note. (1) When you install the .msi for the samples, it will say November CTP. Disregard -- this compiles with the February 2006 CTP. (2) The video carousel is a bit flaky, depending on your video driver. Sometimes, the sound all plays simultaneously and you don't get volume control.
BTW, sorry for the silence on the blog: in MIX mode. See you in Vegas.
