I believe you are using the stable repo. I use the devel repo and what I have is just the contrary!
I got a hell lot of updates lately, and I have KDE 4.6.3 on my laptop, everything works just fine now.
The thing is, the developers are preparing the repos and packages for the 2009 to 2011 transition right now. Also as you already know, the new release 2011.1 will be the most up-to-date release.
I also have seen that most of the packages from the devel repo have been transferred to testing. Which means you will get a lot of updates soon, real soon!
