I think the reason why people thought SRK's "end is in sight" was because his last release was literally 1.5 years ago, it wasn't an out and out commercial film either, nor did it make anywhere near as much money as Salman's or Aamir's films had, granted it wouldn't have either because it wasn't the type of film that was supposed to do 100+ crore business.
Simply put, audience has a short term memory, they remember what you did last. Salman's had back-to-back releases and his films went on to do exceptional business..while SRK's films have been blockbusters but haven't made the kind of money that Sallu and Aamir's films have in the last few years--hence all the oh his career is going downhill, he's going through a bad phase, etc. The real testing time is NOW. If Ra.One and Don 2 go on to break records, he ain't going anywhere.
All in all SRK's had a pretty consistent record at the BO so far, touchwood...his last flop was a good 6-8 years ago with Paheli.
As for only aunties liking SRK? Well I assure you, me and my friends are nowhere near the age where people will start calling us "aunties.."
