In the AMA earlier this year we were told that the Phore core team would continue and the symapse team would be working independently. Which makes me believe there will be a second whitepaper near or upon arrival of Synapse release. I for one cannot wait.
I am earnestly waiting for the results of the independent projects, being able to combine multiple projects at the same time shows the dexterity and the incredible work ethic of the team and it will pay off massively soon.
