February 18th is the target date for Adobe Lightroom 1.0 shipments, with US$199 being the introductory price (US$299 after April 1st). A new version of Camera Raw (ACR 3.7) will appear on that date, as well. Lightroom public beta uses will find their versions are no longer valid after 2/28/2007, so will have to make the decision whether to purchase or abandon.
One interesting bit in the release version: it has Capture NX like "control points" (called Targeted Adjustment Tool in Lightroom) that weren't in any of the public betas (a few other new features have popped up, as well).
