Addendum:

I just read on Wikipedia that the next new episode of The Simpsons will air in High-Definition. But that's not what's gotten me worried. The opening credits, after staying the same since 1990, will change. This has "HUGE MISTAKE" written all over it, except in one spot where it says "JUMP THE SHARK." Could the end be near?

I know what you're thinking. But the truth is, Wikipedia is usually right. But I mention Wikipedia because I can't find any further information, and the citation for the Wikipedia article leads to the wrong page. However, this is also mentioned on The Simpsons Archive, which is often more reliable, though poorly-written at times.
