Wait what? LOL. The reason why NoDo took so long was because it had to go through manufacturers and carriers. Mango is going through the exact same thing right now. Even the whole Samsung phone fiasco was due to NoDo having to be further customized to work properly with specific Samsung phones even after NoDo RTM'd and had already gone through carriers/manufacturers.
NoDo was RTM long before it came out, it had to tweaked and customized, just like Mango has to be, before its really a final release meant for a daily device.
Mango 7720.68 is a generic release meant to be sent out to carriers and manufacturers to be further customized, tweaked, and bug tested before its meant to be put onto a consumer-facing device. That's how its always been with any piece of software. So to call 7720.68 "final" is not correct, nor is it even wise for people to mess with something that came from a potentially unknown source. Course, no one really cares, they're gonna mess around with their phones, which is why we're all on this site to begin with.
When NoDo was released to the public, it had been customized by each carrier and phone manufacturer before being sent out to your device. Any supplemental updates after that, regardless of whether it was a day after NoDo was released, or a month, was in addition to the customizations already on the device. Might have just been a bugfix, or a small update that didn't get to the shipping product in time, but was made available shortly after the shipping product released.
That HTC update you speak of was targeted to a certain device, not all HTC devices. It was a supplemental update for some HTC phones, just to fix some things, in addition to the customizations already present from HTC/carriers.
