To be honest Goldberg wasn't a surprise and while Jericho was a mystery to me back in the day there were fans in the arena with Jericho signs.
The Internet ruins surprise or the site that reports on the company. Now they will tell you 3 months ahead of time when the contract is expiring or when the no compete clause expire. To have a surprise you would need the TNA to be even bigger or have a name that was well established in WWE before like Angle returning. With new stars or mid TNA stars the WWE will sign them 10 months ahead of time, take the time to develop them in their farm system to get use to the WWE style of wrestling or because they don't want to debut her before Wrestlemania.
To be honest Sting this year could have been a big surprise if he accepted to come work with Taker.
I don't know why people say, not going to happen. I know this is not a topic on Sting, but the guy will end up in the WWE next year or the one after. He said that he wants to do one Mania that it's something you always think about it but that for now he choose to stay in TNA.
But to get a surprise you would need a secret signing from someone that you didn't know had an expiring contract and that is well known to the general public. Sure AJ Styles would surprise 20 to 30% of the WWE audience but the other 70 to 80% would not know about him.

As far as active wrestlers though, Sting is the only one left that would be a big suprise and like most said, not going to happen.
