I don't think there's any "in-room elephants":

- Glimmer 2: Shipped

- Ember/CLI 3.x: Haven't heard anything, but there's not really any features that have been pushed to those versions that I know of. Glimmer 2 was the big roadblock for routable components, which is the feature we're most waiting for.

- Ember Redux: Was not particularly liked by a lot of the core team (from an API perspective), but the ideas it represented were. They're exploring ways to implement this in Ember.

- Ember Data: LinkedIn hired "runspired" and tasked him with improving Ember Data performance. His work will ship with the next version (last version had his initial work which revolved mostly around tooling)

- Flexi: Was never really a core Ember project, and I don't think it was widely adopted. It was a runspired thing, and I think he's being kept busy on other stuff (core projects and smoke & mirrors)

I don't use fastboot so I can't comment there, but I see new versions coming out regularly. I also don't know what "vr" refers to.
