According to Google Trends, during the past few years, there has been nothing but a few minor bumps that faded away as quickly as they came. I love RSS because i do not have to scroll through dozens of different news sites all day and i would love it to return.
EDIT: Typical case of people only reading the headline. I was asking why people are hyped over something that did NOT happen.
I'm not sure if RSS usage has really fallen. Most websites still have RSS / Atom feeds, and I hear about a lot more people getting into it these days. I'm sure the proportion of people using the internet who use RSS feeds has gone down a lot, but in absolute terms there might be as many users as ever? Maybe it's not quite at the heights it was when everybody was using Google Reader, I'm sure quite a few people gave up when that died. Though, if you count podcasts as RSS then it probably more than makes up for it!
