Crimson has answered #2 and #3 well.
As for #1, I feel there are still a lot of features it needs to reach a level where I envision it as a complete package.
Additionally, I am a 'hobbyist' programmer who is learning stuff everyday. I would like 'controlled growth' so that I can grow the infrastructure at a steady pace and overcome associated technological challenges with limited impact.
Lastly, I have a day job that keeps me busy for 65-80 hours a week. So I have limited time I can spend on this project to realize my visions.
Overall I think we may reach a 'release worthy' state by the end of 2015. However, I do not want to commit to any concrete dates yet.
