The MeeGo Roadmap will be developed with an open process that is being set up currently. See http://meego.com/developers/meego-roadmap
MeeGo requirements are defined and managed in a public process and toolchain based on common Bugzilla. See http://meego.com/developers/requirements

MeeGo development continues forward on a six-month cadence. MeeGo 1.2 is scheduled for April of 2011 and it will include a Handset UX release with a complete set of applications, and support for other device usage models.
Hundreds of features targeting MeeGo 1.2 have already been filed in MeeGo Featurezilla, which we are using as a tool to track feature development. The development tree of the new MeeGo version is open and we are starting to integrate the new components right now. The MeeGo 1.2 roadmap summarizing this information will be published soon.
