There will be at some point new exchanges added, but for now we concentrate on wallet development. Mac wallet is coming soon. Followed by a smaller wallet update and then we take some time to develop our initial ideas into the wallet. We possibly need a fork for this because most interesting concepts usually need to be programmed into the consensus layer. So before moving on to more exchanges - we need to decide on couple of fundamental ideas how we approach the future plans and what is needed. Being on an exchange means constant communication with the exchange every time wallet update comes out. So for now we hold back on exchanges, but we have seen couple of community initiated requests on smaller exchanges so this might happen before we plan it ourselves.
