Samsung may want to implement bug fixes with kitkat so I doubt they'll just swap the core android stuff and ship it out. Then we'll have ATT just sit on it for awhile, basically do nothing, and finally release it a few weeks later than it should have been at a minimum.It's possible. It's really up to the end manufacturer to release the final version, then the carrier to bloat it up. Google is just making it less resource hungry and more optimized. I really hope that they are going towards being completely modular. Upgrading to 4.4 could (should) have been just updating with a delta file that changed what needed to be changed without involving samsung and att.
