It's really sad that Roy was dropped so quickly despite being the FE character that started it all in the west. The first English FE featured his old man, Eliwood, and Roy himself at the end. Even if Roy's character in the Binding Blade isn't all that, I think he deserves more just for his value as a Smasher and a representative of the franchise. Marth represented the beginning of FE, Roy represented the global beginning of FE, Ike represented the (3D) console debut of FE, and then I don't mind a 4th slot for the most recent installment. Awakening really shouldn't have gotten both Robin and Lucina, and opting for Lucina instead of restyling Our Boy was kind of a slap in the face to people who appreciated the distinct style that Roy supported in Melee and expected. It was more than just 'no tipper' and 'T3H PH1R3' despite how we joke about it. He was a character focused on aggro play and strong, short aerial combos and juggles, someone who could continually dish out damage until they pulled off an explosive finish.
But instead we got Lucina. Plain ol' Lucina who is really just a more pressure-oriented Marth. I'm still keeping faith that Roy is planned as DLC, resuming the work that Nintendo originally had planned for Brawl but lacked the time to finish, and we'll see him as more than a mere Marth 'clone.' I also wouldn't mind FE getting an extra rep, because I simply believe the characters in it are infinitely more interesting than the other big name franchises that survive mostly off of nostalgia and care little for supporting a diverse cast. I've always felt that many characters repping games like Mario are more symbols than they are characters.
I can't really respect Ike has a replacement, either, since the only thing they had in common was fire. Ike is too sluggish and predictable, whereas Roy benefited immensely from overwhelming the opponent with speed and precision.
