Decred and SIA ASICs are around the corner, not sure if its worth to develop dual mining for those algorithms
We'll see how fast they will ramp up production. Given the past history it would take some time before the GPU mining for these coins becomes obsolete.
They sold 3600 units in first batch that supposedly is coming out in June
By their estimate, that will bring about 3200 TH/s to the network, that is currently running at 350TH/s
Then again, baikal announced their ASIC too, that should work with all algos currently used
by Claymore for dual mining, so I guess no harm done adding support for few more months
