RAIN ON PARADE TIME:

From the general words he picked and what he said, it looks like he's been talking to publishers rather than developers at Epic. What tells me that this is actually more than it seems is this line:
"everything’s kinda gone quiet on it."
It sounds like he's been having trouble getting a team of developers interested, especially because the "pitch" is 2 years old as it is.

Overall, it looks like CliffyB does really care about the stupid rabbit game, but developers don't want to dedicate any time or effort to it. They're all too busy with other projects to get started on this one.
