if I had to guess I seriously doubt it. I think the only mod they will HOPEFULLY make is a 8GB card on the 470. This one is less expensive to make with less fans, metal etc.
Agreed on the 8GB. These days, I don't think 4 GB cards are certain to be future-proof. Example: if ASICs come out for Zcash, they will probably mod the Equihash parameters so that 8 GB is necessary for best performance (4 GB will still work, but at a decided lower solution rate). It's not a likely event, but when you're spending this much money, you'd like to think it will produce at high performance for years to come.
zec may switch to 8gb really soon. if you buy these don't make it your only gpu miner.
I have rx 480 8gb rigs
I have the panda rx 480 4gb
To not have a mix of 8gb and 4gb and go all 4gb is not so good me thinks.
