well I certainly hope SRK doesn't follow suit. He deserves a break after working continuously for 26 years. Not just that, in the break time, he still has ads to shoot, TED talks, other interviews, public appearances, production work, and a lot of stuff.
But I hope that once he actually reruns to shooting, he starts releasing around 3 movies in 2 years. Reports do suggest that he will be shooting his next 2 movies together.
BTW SRK's pace slowed down from 2007 onwards.
In 2008 he had just 1 movie, that too more than 1 year after his last. In 2009 it was just an extended cameo. In early 2010 he had 1 movie and then after 1.5 years wait he had 2 movies released in a span of 2 months. After that around 10 months for JHTJ. Another 10 months for CE. More than a year for HNY. More than a year for Dilwale.
After that he had more volume in 2016 and 17 mostly due to movies getting delayed and long shooting processes. But once again he took around 16 months for Zero. So in general over the last decade he has already reduced volume to 1 movie per year. Hope that increases.
