The 33-year-old "Super Dan" said after losing Sunday's showdown to Denmark's Viktor Axelsen in Glasgow that he would immediately return for China's National Games and then play at next month's Japan Open.
"After that I have no plans," said Lin, indicating he might soon call it a day. "It will be difficult to play in the World Championships at 34."
But the two-time Olympic and five-time world champion, regarded widely as the greatest singles player of all time, mixed his message by adding that reaching the final against a player 10 years younger "showed that I am still strong enough physically".
Lin was the bad boy of Chinese sport in his younger days, with a rap sheet that included hitting a coach. And he has hinted at retirement before, only to plough on.
Lin proved his enduring quality in Scotland by beating South Korea's world number one Son Wan-Ho in the semi-finals, before going down to the 23-year-old Axelsen in what felt like a changing of the guard.
"It is unbelievable to beat Lin Dan, I have been watching him for years," said the Dane.
As he nears the end of his career, Lin has been cherry-picking his tournament appearances to help extend his time at the top, like 36-year-old Roger Federer who has enjoyed a resurgence this year to win two tennis grand slams.
Lin has fallen to seventh in the world rankings and fans on China's Twitter-like Weibo, where he has 3.75 million followers, said he lost the final to Old Father Time rather than his Danish opponent.
"The best players will always lose to time and/or age in the end. Even in defeat Lin Dan deserves to be honoured and respected. You will always be Super Dan," said one.
