Our goal is to support Eth and BTC (and other popular blockchains such as Lisk in future), enabling true multi-blockchain DAO's via Wings.

We are quite aware of a certain ICO/DAO "fatigue" lately, and are actively discussing the best date to schedule the Wings DAO.
Moreover, the Wings DAO will only start after we have the white-paper, prototype / testnet up and running and other tools and materials.
