So, let's go ahead and get the depressing news out of the way: Shonda is not writing the finale Didn't We Almost Have It All? I know, I know. It totally sucks. But she isn't. Instead, the writers of last year's amazing Deterioration of the Fight or Flight Response are writing it - Tony Phelan & Joan Rater.
Now, let's go ahead and get these depressing rumors out of the way: These are the same rumors we've heard before, but now they're getting bigger coverage because some of them are true. According to an article in the National Enquirer, Isaiah Washington AND TR Knight are BOTH leaving Grey's. In the finale, Burke is said to get passed over as chief and leave Cristina at the altar, paving the way for him to leave. George is said to have failed his boards and doesn't want to re-do his internships, paving his way off Grey's. Derek is said to not be sure about his relationship with Meredith, because there "might be another woman." And Jane Doe's husband arrives. According to Michael Ausiello, some of those are true. But he won't say which ones. Hopefully, only the one about Jane Doe is true. However, I could see the IW one being true, although I really hope that doesn't happen.
Alright, depressing news is over. On to some happy things! We were all disappointed at the fact that this year's finale would only be an hour, but, in fact, it is a little longer. Not one-and-a-half or two. But, it is a 67-minute finale...a little bit longer!
Also, the description has been released for Didn't We Almost Have It All? which can be read right here.

As for now, that's all. More news will come later as more things develop.
