Yup. Preordered mine yesterday from Best Buy. I was only the 25th preorder and they anticipate having over 100 Fires in stock for Tuesday. By their own admission they had done zero promo for the preorder. They weren't even sure yet where they were going to be placed physically in the store yet. I think Amazon is going to sell a ton of these (assuming they work as well as they did in the demo units) once word gets out. Finally saw a TV ad for it yesterday.
