During the Developer's AMA, the Core developers announced this years roadmap.
They announced that we will definitely be getting these:

• SegWit
• CoinJoin-like features
• Sidechains to test block scaling BIPs (101)
• No RBF

Whilst no block scaling method has been announced publically, I am certain there will be an announcement very soon.

There are also developer effects being taken by also the Litecoin Association. This includes a new website (with crowdfunding, dev help, project management...), videos on the Litecoin Association channel (available here: youtube.com/user/LitecoinAssociation, iOS wallet, fixes to LitecoinJ and the Android wallet. There are also some others I haven't announced, only because I'm currently taking them as a personal project, but if and when those are at a good enough state, the LA will announce those.
