What are possible planned blog features?

[Andre601]

From the insiders page is it known that a blogging feature (most likely through a plugin) is planned.

Before I now go and suggest already planned features for it, would I like to ask first, what the current plans are for it?
What should be the core features? What other stuff is considered?
