I somehow anticipate that an expansion of "Tech" to a "FF Tech line" would make sense, be it with 47mm or 45mm case and rubber straps similar to Act II. A long stretch from the fantastic originals in many ways, but very close in terms of the original concept. My take (and hope) is that they follow the concept.
It would also make sense to upgrade the titanium used for 5010 to the 5015 iterations.
