No to be a Doggie Downer but it's a bit debatable. For example last year there was only 6 daily deals on a rotational basis for Autumn whilst the Summer and Winter sales both had 12 with all 3 having rotating Flash Sales every 6 hours. 2011 they all followed the same format (12 dailies on rotation) and 2010 was The Great Treasure Hunt. So it's been the lower key sale in recent history though all Steam Sales are big in scope. But hey you never know Valve might mix it up again. Just over an hour to find out.
You're misremembering: the Summer Sale had nine Dailies whilst the Autumn and Winter Sales had six. I should have clarified that by "scope" I was referring to the breadth of the discounts: i.e. virtually everything is discounted and select titles are promoted further as Dailies/Flash Sales/Community's Choice items. This is in contrast to the Halloween Sale during which only titles that fit the theme are discounted and there are no special deals.
