Hi guys, Sent an email to the Sonnet Guys about the Echo Express III-D Desktop Thunderbolt 2 Expansion Chassis: 1. Will you continue to upgrade this case when future versions of Thunderbolt are released (i.e. Thunderbolt 3+)? I notice you don't sell the original Echo Express Pro anymore so that is unlikely to be upgraded. The Echo Express III-D, unlike the previous Echo Express models, is upgradable (the Thunderbolt cards plug into a PCIe slot on the backplane,). The upgrade from Thunderbolt 1 to Thunderbolt 2 is as simple as replacing the card. We expect the Echo Express III to be upgradable to future versions of Thunderbolt, however the nature of the upgradable to Thunderbolt 3 won't be determined until that technology is released. It could be another simple TB card upgrade, or, if TB3 is Gen 3 PCIe, then it will require that the backplane be upgraded as well. I suspect we have at least until 2015 before we see another generation of Thunderbolt. 2. When will the Thunderbolt 2 upgrade be released? We expect the Thunderbolt 2 to be released sometime between mid December and the 1st week in January. While we do have a Mac Book Pro with TB2 in house and everything is looking good, we want to have had the Mac Pro for a few weeks of testing before we release the cards. Thinking of getting one and a top spec Macbook Pro (without NVidia) but wish that some of the Linux distros had support for hidpi screens (want to dual boot alongside Windows for egpu use).
