So I am not seeing this upgrade in any 12.04 bases. I have no choice
I must install KDE on 13.04 and find out!
Mangaka is definitely on 4.10.3, it's the only environment that still works. Originally a 10.04 with Gnome 2.
Edit..time passes
Looks like 4.10.2 to me

time passes
Definitely 4.10.2
Well that..sucks.
I can't help but wonder if it is the developmental...and..I think I know it is..but..
Goodbye 13.04
I already have Saucy on my netbook..and I guess Mangaka..lame..whatever..
sudo do-release-upgrade -d
more time passes
Ahh..well..I did not know developmental did that with KDE. Just the above command brought it to 4.10.3. Gnome is at 3.6.3.1, and broke, freezes up when applications is opened, Unity and Mate are fine. Interesting, but not worth anything. I really had to know though. So no 4.10.3 in backports, least the ones you would want.
