Seriously? No more biased that pointing out the "captain obvious" statement that 480 will be the best selling card. Since it is the only card on 14nm, it would be a fail of colossal proportions if it were not.
I guess I should have quantified my prediction.
There will be two more 14nm cards at lower price points very soon. However the $199 4GB Rx480 hits the sweet spot (price/performance) for mainstream 1080P gaming and entry level VR (although VR still isn't ready for mass adoption yet, it's just being used for marketing purposes by both sides). Thats why I'm "predicting" it'll outsell the 460/470 and probably the Geforce 1060 this year.
It's just a guess but I don't see anything else really competing with it. If the leaked 1060 benchmarks are real, they're not big enough of a difference to warrant the price premium. Now I'll change my tune if Nvidia takes a hair cut on margins and prices the 1060 more competitively.
Besides gaming the real elephant in the room is crypto currency mining. The 480 has proven to be the optimal mining card. Geforce cards have always lagged behind in this area and given the specs, the 1060 will not dethrone the 480, or even if it could Geforce cards simply do not work well under Windows for mining ether (which a ton of miners start out on).
Speaking of Ethereum - it isn't going away and the DAG algorithm is effectively ASIC resistant so the demand for 480's (and likely 470's) will continue to escalate. Even some of the larger government subsidized Bitcoin mining farms in China are starting to stand up Ether farms.
Any semi serious miner has at least 10 - 15 GPU's running. So even if miners make up a tiny fraction, they buy up a disproportionate amount of cards.
