Scores of hopefuls audition for the judges each year, before they pick just forty to proceed to the live shows.
However, Simon is already looking further ahead - and he's already picked out the two acts he reckons will become big names after the show.
"If you can find one star person in the series then we’re doing well," he commented.
"Right now I think there’s a possibility for two, there’s real potential."
It's unclear who he's talking about, although fellow panellist Alesha Dixon is backing singers to win this year.
The Syco boss also told how he changed has his approached to judging, by considering other perspectives.
"I definitely looked at the show in a different way to previous years in that I was much more aware of what was going on, what I like, what I didn’t like," he explained.
"You have to stand by your own opinions, but you also have to accept that stuff you don’t like, others may do."
Meanwhile, BGT presenters Ant and Dec teased that viewers will see a variety of unexpected new talents.
Ant says the range of weird and wacky new displays has made the new series feel "old school".
"We got some really well rehearsed, polished acts that came on and surprised everybody and, of course, a load of crazy stuff where you think, ‘Where the hell did you get that idea from?!’" revealed Dec.
"It shows there are still people out there who are willing to try new things. It’s been great," smiled Ant.
"It’s felt a bit like old school Britain’s Got Talent where people used to just practice their act in their bedroom and then turn up on the show."
"We had a load of people telling us this is the world premiere of their act," added Dec.
Britain's Got Talent is back for its thirteenth run tonight at 7.15pm on ITV. Stephen Mulhern follows with spin-off show More Talent at 8.35pm on ITV2.
