I don't really see this will happen but if the price of bitcoin will be more stable i can see that more retailers accept Bitcoin will happen. But as of now, i don't think casual people, whose not techy one , maybe will not consider this as a fancy thing, or maybe if bitcoin will be a trend a mainstream trend, for sure many people will bandwagon/fanatic of bitcoin, in that time i think more retailers will accept bitcoin.
I think, legalization is the main obstacle in way of practicing bitcoins in daily life. Retailers do fear accepting payments because of illegal nature of bitcoins. And bitcoin can serve as a good method of receiving and sending payment from their reciever and sender.
