Even if we're talking about such a massive roll-out to millions of machines, with various versions of the OS running on various hardware? I don't know how easy or not the actual patch is to produce, but it's not out of the realm of possibilities that they did run into a compatibility issue that they wanted more time to sort out. Think of the outcry and damage to their business if they rolled out a patch that accidentally broke some installations.
