Disneys research arm have come up with a new way to key that they say gives a quicker, better result than traditional keying and despill tools.
They have rolled it into a Nuke node but as of yet it is purely an in house tool (quite possibly will never be released to the public but they have released the research paper so odds are some boffin might cobble together their own version).
Check out this video for an overview.
They have published the paper in PDF form which you can get here.
