If they can get Future World refocused, I think Epcot can come back pretty easily. But it's in such sad shape right now that it doesn't surprise me at all that it's fallen behind. What says a lot is that it's below Hollywood Studios, which in many ways is in even a worse mess, at least until SWGE opens later this year. And that's with all of the festivals they have at it in an attempt to prop up the attendance.
The new additions will help some- I think the space restaurant fits great, and even though it doesn't fit at all with the park GOG will likely be extremely popular. Ratatouille is a fantastic fit in France, and for many will make it feel like there is something to do in World Showcase. I have to disagree with Andrew Appleby above- I thought Ratatouille was a great ride, so very much Disney, and I think it's going to be a huge hit.
But even with all of those, I still think they need to fix Innoventions/ Communicore, which just gives you a head dead space right in the middle of the park when you first come in- a terrible first impression. Many other areas also need obvious help and improvement, the front half of the park needs a refocus and theme that ties it together, and for most families I think they're wanting to see another ride of some sort in World Showcase, somewhere around Italy, Germany, or the large space between Germany and China. I don't see it recapturing #2 until those issues are addressed.
