In my opinion that answers your question.
If you want some kind of time line on how long each Dev Bundle takes I found this thread for you.
It seems like a very similar question to your OP with a response from David.
I hope it helps.
Your question has been asked time and time again, like I said
Do people need to do the research for you? A simple search should find your answers as to why the network didn’t launch last year. The dev updates are consistent and give an idea of what is going on right now, there is also a Roadmap describing planned projects.
Saying the network would launch last year was a mistake on the part of MaidSafe, do you want them to make another mistake by saying, for your sake, it will launch in 2-3 months? And if it doesn’t what is their credibility then?
Can’t we just let them work on their project and do it well which they are then going to turn over to us for FREE? blimey.
