[RCD] roadmap dates? vNext?

I know this is the kind of question people hate, but is there some sort of rough notion (say, to 6 month precision) of when the major releases might come out? And is "vNext" the same as 0.2 or 0.3?

Looking at http://trac.roundcube.net/trac.cgi/roadmap the plugin API won't be til version 0.3.

I ask because I'm contemplating using roundcube as the basis of a corporate messaging workflow app and would love it if my extensions could be implemented as plugins (for example, a plugin to generate and run forms to create documents to be emailed). I've looked at Zimbra and Joyent, and unfortunately they don't really have plugin support either; extensions require modification of numerous core files.
