From what I understand it looks like this.(please correct me if I am wrong)
Create BTS ,a master/mother DAC with a new DPOS blockchain and UI client.(with a fair allocation of Bitshares to BTSX/AGS/PTS holders )
Integrate all other existing and future sister DACs into it(BTSX,DNS,VOTE and Music), using BTS DPOS for all sister DACs transaction generation with cross chain transaction implementation for bit-assets.
All this to create much more healthy environment for developers and bit/fiat assets markets (the main currency in this network will be bitusd I suppose)
