I see day by day, ASICS of many coins are launching, individually or multiple. Chinese companies are trying to kill the GPU mining market once again cause they are greedy, just like they did to Bitcoin and Litecoin. GPU Mining died in 2013 and was resurrected in 2015 with the Cryptocoins Generation 2.0, although many of you miners just started mining on 2016 due to huge pumps on those 2.0 cryptocoins.
Realistically speaking, GPU mining won't be dead any time soon. Just because ASICs are available doesn't mean there are enough of them to power all blockchains. Running an ASIC at home is much more difficult and riskier than running a GPU rig. It's much simpler to get a GPU than an ASIC. etc.. Also don't forget that new GPUs are coming out every year.
