I wouldn't be surprised if we get the same result but couple of different reasons for me

I think Crono/Bowser fans are more likely to favor Mega Man than Link/Ganon fans and you are forced to vote in both matches. I don't have a particular reason for thinking that, just a gut feeling.

I think people are people are more apathetic in the losers bracket and I would think that Pikachu would gain more of that casual/apathy vote that is lost.

In a close match, especially one repeated so soon afterwards I get the feeling that the result will either swing the other way or no longer be close. Pikachu likely got the underdog/momentum vote first time around and is less likely to get it the second time around after already beating Mega Man once.

People are probably less likely to rally in a losers bracket rematch (or the original losing side is more likely to rally) which probably favors Mega Man. Hey rally this person to victory over the same person they just beat last week doesn't quite have the same luster to it.

And basically only 1-2 of the above have to be right for the result to swing
