There are many related BEER projects.
- Open Subdiv [Updated after the discussion on irc #blendercoders]
These projects intersect with BEER. Thus it is best for us to work together to upgrade them. Think of BEER and related projects as Blender 3.0

Looks like our plan to be internal has been misunderstood by Ton. So we decided that to go full force for an external renderer path and not stay at the mercy of Ton. BEER should be the tool for artists, not Ton's alone.
Sad to see BGE, Viewport & Blender Internal Renderer in the losing side of this decision. The community has a say too.
Update 2014/11/10: Looks like going the external route was a big mistake. Not only Blender will not get BEER goodness, BGE, Viewport Blender Internal Renderer will not get the attention they need. Thus the team decided to talk to core devs to solve this.
Update 2014/11/29: There will be an OpenGL GLSL renderer in Blender. Official announcement next week.
