We will have a roadmap soon, and certainly before the fundraiser begins.  First we will complete a production version of Tendermint, tmsp-ethereum, and adapt tendermint/basecoin into an alpha version of the hub.

* github.com/tendermint/tendermint
* github.com/tendermint/basecoin (not complete)
* tmsp-ethereum will be announced soon

Cheers,
