They centre around retirement, which gradually edges closer for the two-time major winner.
As they were after the US Open, Hewitt's answers were largely non-committal following his second-round exit at Melbourne Park on Thursday night.
"As I said the whole time, I haven't been kidding anyone, really I don't know," he said when asked if coming back for a 20th straight Australian Open was a lure.
"I've just tried to focus on what I've wanted to do, to get the best out of myself this year. I'll sit back and assess everything after this tournament."
The year, however, is not yet a month old.
Hewitt, who turns 34 next month, is ranked 87th in the world – that only slipped after he failed in his Brisbane International title defence.
Since February 2013, Hewitt has maintained a top-100 ranking.
Some perspective is often required when discussing Hewitt's future.
The Australian veteran is still ranked among the top 100 players in the world of a sport in which just getting to that level is a goal for some.
Sure, his recent grand slam record makes for disappointing reading.
Five of his past eight exits at majors have been first-rounders, and his last quarter-final was at Wimbledon in 2009.
But there is more than just slams to play for in the twilight of his career.
Hewitt has 46 ATP World Tour titles, two of which came last year, and he has been in five finals since 2010 – four of those on grass.
His ranking is likely to improve after bettering his first-round exit of 2014 in Melbourne, and he has few points to defend between now and the grass-court season.
With a little bit of luck, Hewitt could improve that ranking before June.
He is thinking about the Davis Cup tie against the Czech Republic in March, and Australia still need him.
Hewitt may be the fifth-highest ranked Aussie, but his maturity and experience is crucial around the likes of Nick Kyrgios, Bernard Tomic and Thanasi Kokkinakis.
"Obviously it would be great to play when Nick and Bernie and Thanasi are possibly top 10, top 20 players, you get a free ride winning Davis Cups," he said with a smile.
"That ain't going to happen straightaway.
"You know, I've always said that for me to stick around in Davis Cup is to help these guys more as a mentor, teach them what Davis Cup's all about.
"So far I've been able to do that from I guess my dedication on the practice court and the match court playing for Australia."
Injuries could yet decide his future, but the Davis Cup and winning titles are likely to be motivation enough.
See ya in 2016 in Melbourne, Lleyton.
