Based on my experience with large companies and development release cycles, doesn't matter the partner they will always adhere to release cycles. SOE probably has a firmware release cycle that just came up and that's where they stuck the fix. You would be surprised how even one line of code can take to make it to production regardless of the "motivators", even if the fix is identified immediately, it can take some time to document, verify, GA, test push to a subset or all devices for the fix to validate before they get the blessing to go public. With a company as big as these two it's kind of surprising that it happened this fast.
