This is one of the improvement MeeGo will bring. OSS platform work totally detached from specific vendor plans. If MeeGo wants to have a roadmap with dates they are free to decide that, but a Maemo 5 roadmap with dates is another different story. One day users will be able to run 'MeeGo unstable' in their devices with updates of whatever OSS components are there integrated. This connected with git repos, bugzilla, even variants with more experimental stuff... the real OSS deal. Maemo 5 still has a mixture of open/closed & upstream/nokia/3rd parties that is difficult to separate at a release/repository level. Also the "hard" API layers of Qt and Web Runtime will make it easier tu run unstable OS while still keeping your chances of seeing your apps booting every morning and running properly.
