Do four sentences on a wiki page that amount to "we should make something" constitute "preliminary work"? If that's true, I'm starting preliminary work on a space shuttle tomorrow.
Seriously though, FlightCrew will have support for epub 3.0 when it's out and when people start caring about it. The latter will probably come much later than the former though.
