ABC News' Michael Falcone reports:

Donald Trump is keeping his Republican National Convention role a secret for now, but on Wednesday he hinted that whatever it is - it's going to be "pretty wild."

The real estate and reality television mogul who has remained in the 2012 political mix even after declining to launch his own presidential bid last year said in a pair of interviews with Fox Business Network's Don Imus and Fox News' Neil Cavuto that he had been invited by the Republican Party to speak at the convention in Tampa, but that he may have even bigger plans in store.

"They've asked me to speak," Trump told Imus. "I may do it, but I don't think you can do both. And you'll understand when you see what I'm doing. So, it will be one or the other."

Trump added, "I am doing something that I think is going to be I think really amazing. It's going to be great. And we'll see what happens. I mean, we'll see how it's received. But it will be pretty wild. I think it will be potent. We'll see."

It is likely that Trump's "wild" appearance will take place on the opening day of the week-long convention that begins on Aug. 27. One day earlier he will be receiving the Statesman of the Year award from the Sarasota Republican Party.

Earlier this month an aide to Trump said he would play a "major role" at the convention where delegates will officially nominate Mitt Romney and Paul Ryan to the GOP presidential ticket.

In Wednesday's interview, Trump described Romney's decision to tap Ryan as his running mate as a "bold choice."

"There's a lot of revitalization going on right now in the Republican Party," Trump said. "A lot of people are very happy about it."
