If this was a list based on tourney usage and match-ups, then I would say no, Mario is not better than Ike.Still, do you think we'll be seeing Mario move above Ike?
This is a list made by the collective votes of a the back room, however; unquestioned opinions. In such a situation it's really difficult to try to imagine what the thinking process of these posters will be at the specific moment in which they will be required to give input for tier list version 3.0.
I don't particularly approve of such a system, mind you, I would prefer each character be individually analyzed and compared based on the characters around him/her/it and in the process everything should be looked at: Match-ups, tourney placings, metagame advancements, base character traits, etc etc.
But to answer your original question then go to sleep:
Who knows?
