Suggesting and/or implying that the Canon lenses that are designed and routinely used on 24 megapixel cameras and used by top professionals in areas (like print magazine, fine art prints, etc) that can actually use that resolution won't be sufficient for 13 megapixel Epic is sort of silly.
As far as lenses wider than 14mm - Except for possibly the new 12mm MP and maybe the 8mm UP (anyone checked?), virtually none of the "real" cinema lenses like the UPs, MPs, standards, supers, Cooke's, etc. etc. even COVER the 5K sensor. And the Zeiss Compact Primes are just converted still lenses (which is why they cover FF35), which bolsters the still lens argument.
We have already shot the Ruby 14-24 (converted nikon still lens) underwater on Epic and it works great, but we are looking forward to a Canon mount to use even wider lenses, without paying the 800% premium of having to get a converted still lens on a PL mount.
And let me reiterate, we have been extremely happy with Canon lenses on the Redone and have no real interest in PL on epic. For any customers that need PL we would just rent the mount along with the lenses.
So I would really like to see the option of getting the Canon with our Epic-X rather than the PL, even if it means taking delivery without a mount.
I have twenty Nikon mounts leftover from the AquaLens Nikon to Nikonos conversion units that we bought surplus to get the dome ports - making a Nikon dumb mount for the interim would be extremely easy for any halfway competent machinist - it's just a properly sized block of metal with four mountholes and some relief on the back, and four holes for the nikon mount that is a $20 stock part from Nikon - not as slick as Jacek's or Red's planned one for epic (with the positive lock) but the lens mount itself is just like the one on the RED1 Nikon mount and it works pretty well for millions of Nikon SLR owners. The Epic body mount design is much nicer so install is much easier than on a RED1.
