From what I've gathered:
-Red drives and Red Ram are EOL and no more are to be made
-Red 16gb CF is the last Red CF to be made
-SSD is the only media fast enough to be used on Epic's HDR and high speed data modes.
In light of these developments, it seems that it makes no sense to ship the EpicX brain with CF being the default module. That used to make sense, back when there was going to be a 64gb card (which was killed off without explanation).
Unless I'm missing something here, it seems SSD for Epic is the ONLY choice, with CF only good for Red1 and Scarlet.
