The 52-year-old, who heads the highly-successful football conventions and forums company Soccerex, had said he was not yet ready to join the takeover race.
But he has now confirmed he will decide by the end of next week whether to make a formal bid for the club.
Revie said: "The creditors meeting has never been a deadline for me. We have a much longer-term view of taking on the whole thing and will not be rushing into our judgment.
"We have lodged proof of funds with the administrators. We have not lodged a bid. We need to see the figures first and you don't get to see the figures unless you can prove you have the funds available.
"By the end of the weekend we'll know whether or not we're going to make a bid."
It has been reported Revie is heading a Dubai-based consortium, but it is now understood he is working for an individual backer.
Revie added: "That person wishes to remain anonymous, but you could probably guess who it is if I say the financial backing is coming from the Middle East."
It has also been reported that other consortia are aiming to ambush Bates' plans to resume control of the relegated club, including former Leeds director Simon Morris and ex-West Ham chairman Terry Brown and two Irish consortia.
But Revie is not concerned who emerges from the meeting in control at Elland Road.
He added: "Whatever happens at the creditors' meeting it will not alter our plans at all.
"We have an unswerving vision, just as my dad did when he walked into Elland Road in the early 1960s and changed the strip into the all white of Real Madrid.
"If I do this I will do it wholeheartedly. I have a very talented team of legal experts and accountants who are looking at it.
"It's a heartstrings and head decision. My heart's going one way and my head's in the middle. Hopefully we can bring the two together."
