Algorithms that are still protifable mine on GPUs were designed with ASIC resiliency in mind - they use memory hard algorithms. This makes the problem of designing specialised mining cards equivalent to designing fast and efficient DRAM, an area where the consumer product is the cutting edge. This was by design to reduce hashrate centralisation. Even the latest ethereum ASICs are only 10% more efficient, cost much more and can only mine ethash and its variants. So as it stands I see no evidence that suggests mining cards will be cheaper with better efficiency, especially when the cryptocurrency community slowly moving away from mining.
