There's a roadmap here >> https://maidsafe.net/roadmap.html#network but no dates though, best is to follow the weekly updates on the forum. In the coming months we can expect this:

• TEST 12c - Better routing with disjoint groups, bugs removed, might be the last test before we'll see Alpha 2. Alpha 2 will allow people to support the network from home with Vaults.
• The SAFE Browser with Authenticator - This will bring us just 1 tool to connect to the network, create an account, upload data/websites, run Apps and more.
• Loads of APIs so devs can connect their Apps to SAFE.
• Alpha 2 - People can connect using the browser like explained above. People can support the network by running a Vault from home.

This is it a bit. After this they will implement "Data chains" and "Node ageing" probably with "Archive nodes". All needed to make your data last forever on the network if you prefer. This sounds like a bit more work than it actually is. There's already a bunch of code for the datachains here: https://github.com/dirvine/data_chain
Think of it as certain Vaults storing all groupdata. So if the internet ever goes down, SAFE can republish all data and accounts without any problem.

I expect TEST 12c this week. If all works as expected they'll move to 'Alpha 2' while working on "data republish" for the coming weeks. Meanwhile a lot of work on the APIs and front-end as well.

Hope that clears things up a bit.
