The FPGA is indeed doing the glue logic to the Epiphany, but that's only one of its functions; there's plenty of space left for other jobs, one of which is HDMI output. They do plan easy access to reprogram the FPGA, but since Xilinx synthesis tools are only available on x86, you'll also need a PC to make new FPGA configurations.

Will we have the source for the module that ships with the board so we can synth both it and some custom logic to go along with it ?

YES, you will get the source code for the FPGA logic.
