Thunderbolt is dead anyway, Only apple really uses it, and the fact their arent a lot of accessories for it and the ones that are out cost an arm and a leg due to lack of demand and the cost of using thunderbolt, leads me to believe it will forever be a very small demand and will be over taken by future USB standards.
The fact USB type c can take care of power, data transfers, and display output like the Thunderbolt now, is even more reaosn why Thunderbolt will eventually bite the dust.
USB 3.1 can also technically transfer up to speeds of 10Gbps, Which is more than enough and also will get better as each revision does.
