Now that they did some black friday deals on S4, I am pretty sure once S4 is sold out they will announce S5.
What black friday deals?
there was a scam site which robbed people, offering massive bitmain discounts. perhaps that news hasn't filtered through to some yet.
This is true, but they are also selling S4s for 30% off and free international shipping, but you need to buy at least (I think it is) 16. Even with those prices the difficulty will need to rise very slowly for you to potentially ROI.
