The 13.04 release will be a normal one, and will probably be the last release before a lot of changes to how Ubuntu will handle releases will change. Although I neglected to cover all of the changes, I think that this time around Omg Ubuntu pretty much covered everything they could. I suggest you look at their news feed.
I'm still debating on whether I should look into taking a look at all of the Ubuntu spins, and the main release, like I did for 12.10. I'm pretty sure I'll look at Lubuntu, and the main release. Xubuntu and Kubuntu will probably be looked at by request, so if you want me to look at it let me know.
So...just 10 days away. Are you excited?
