Technically they are change coming in Patch 2.5 and the thread is the same that Slouken posted his April Fool’s joke about the combat log. You can actually see my post just above his latest one hehe.

Anyways, I say that this change is something regarding the expansion because lately I have been seeing a lot of different elements at play with the UI and the raids that seem like Blizzard is making some game wide changes. For example the hidden buff in the Sunwell Plateau that essentially steers towards bosses no longer landing crushing blows. And now this post by Slouken.

We are actually working on converting Blizzard code to use self instead of this, but it’s for the expansion. I definitely recommend authors start using self, since this and argN are deprecated and will go away eventually. (src)

With the new tech and new code that Blizzard is developing to use in the game I can only speculate that these changes are going to come full circle in the WOTLK expansion.
