The very fact that Roy didn't make the cut for Brawl signifies how important he is. Ike had priority over Roy. What will happen when Ike doesn't make the cut for SSB4, with his files unfinished and hidden in the code as well? What happens when Chrom makes it in, Ike is stuck in limbo, and Roy is nowhere to be found?
More arguing on smashboards. Relevancy is important, as you pointed out with Mewtwo. Roy is irrelevant now. Sure, he'll appear as DLC in FE: Awakening, but according to the rule of Ike, a main FE protagonist is more likely to get in for the sake of evolving both FE and Smash Bros. Now, if three FE characters are to appear in SSB4, it would most likely be Marth, Chrom, and Roy.
You talk as if it is going to happen. So not only are you part of Brawl's development team, you are an oracle too? Just digging yourself a deeper hole.
Oh, and what's this? You actually beleive relevancy is important?
Go back to Gamefaqs, kid. I'm pretty sure they'll buy that bologna.
I mean, it explains why the likes of Ness, Jigglypuff, Sheik, Ice Climbers, Marth, Mr. Game & Watch, etc. were axed from Brawl, and why we didn't get characters lke Pit, Pokemon Trainer Red, R.O.B., etc.
Even funnier is that you believe Roy and Ike got in because they were the latest Lords. This is false. Roy got in prior to his debut in his own series, so on technicality, he wasn't the latest Lord. He pretty much
didn't exist yet. Roy was chosen to promote the upcoming game, and according to Sakurai, to "promote the Fire Emblem series as a whole".
Ike got in because Sakurai wanted a newer (note: not newEST) Fire Emblem character, which meant that he wanted a character simply that debuted after Roy's game. Which there were 4 games to choose from. He went to Intelligent Systems for a suggestion, and they suggested Ike, likely having to do with his popularity (especially in the West), as well as him being in multiple titles like fellow Fire Emblem hero Marth. If the newEST character had been picked, it would have been Micaiah, as she was the newest main character as Ike had debuted in the game that came before hers. (Also, if it mattered by relevancy, why is Ike in his PoR version rather than RD?)
If relevance was not important, Lucario would not have been in Brawl.
Except we can't attribute relevance to Lucario's inclusion.
Contrary to what you may beleive, being from Gen 2 did NOT help Pichu.
In fact, Sakurai had been on record in Famitsu saying that he did not find any of the popular 2nd Gens to be "feasible", despite what fans might think (i.e. fans wanting someone like Scizor or Heracross, who both could work very well).
He only went with Pichu because was an easy clone character to add to boost the Roster (somewhere along the line, he felt the roster was lacking, so he made the 6 clones we know today), and be a joke character with it hurting itself when it uses electrical attacks. He
could have used Raichu instead, but he felt Pichu added more of a charm and made a good joke.
Lucario was clearly a feasible Pokemon, was hugely popular, heavily advertised (even prior to the debut of the Generation it came from), and could offer something unique with it's Aura.
If relevancy was the big issue, we would have had someone like Deoxys instead of the Pokemon Trainer, due to Emerald coming after FireRed/LeafGreen, and Deoxy's movie being
right before Lucario's. It also had great popularity (Sakurai comments on this on the Dojo update). So Deoxys exclusion was not because of relevancy, but because Sakurai must have not deemed Deoxys feasible with it's shifting between modes.
