I’ve been pestering contacts at Microsoft for an official features list for months, and they’ve politely but persistently refused every one of my requests. The other missing detail is the exact breakdown of features in each edition. The last remaining pieces of the puzzle? There’s the price list, of course, which I don’t think will be revealed publicly until close to the on-sale dates. This week, they finally announced the official release dates: RTM next month, on sale beginning October 22. Over the course of its Windows 7 development effort, Microsoft has been incredibly controlled about releasing details, pursuing an agonizingly deliberate disclosure plan.
