Like what? 4.4 hasn't been released for the UK. In fact, it's only been released in less than a dozen region's. No one here knows when a specific region will receive it, why the regions that got it first were chosen, or anything else to do with Samsung's update logic and reasoning. If you have a 600/601 you can flash another region's ROM right now. You'll be able to do the same thing with a 605 as soon as the NEE update that came out yesterday is posted on Samfirmware or Samsung-updates. There are tons of posts discussing how to flash another region's ROM and the implications. If you're interested, invest the time in finding them. Or, you can just wait for the UK update to be pushed along with other folks whose regions haven't received the update yet.
