I am catching up on what has been said in this thread. Shortie actually brought up an interesting point about Chrom in relation to Roy in another topic. That Chrom's being the most recent lord as well as his "blandness" has made Roy's situation better in a way. Prior to Chrom, people were asking for all sorts of weird choices for a FE newcomer (look at Sheeda, she has basically no support nowadays, but back just two years ago, there was people actually saying she was giving Roy competition for a spot). Talk about letting your genitalia doing your thinking for you.
I think with Chrom although he is the second most wanted FE character, that there won't be much bitterness if he does not show up in Smash 4, and he will pretty much end up falling down the memory hole. He does not seem particularly popular among the Western FE fans that have played his game (most of them prefer the My Unit or Lucina). There is not really much about him that makes him stand out.

I don't it would be hard for Sakurai to de-clone Roy considering that even the fans have a lot of ideas on what do do with him. I think more fire flashiness is a major plus and will probably happen if he returns. I don't think Roy could even have to share specials with Marth. He could easily take Eruption from Ike (while Ike gets an axe special), has a special based off of the Sword of Seals having the ability to shoot fire, and a special based off the Sword of Seals's ability to heal. It also should not be too hard to come up with an unique recovery move and Final Smash (I have already seen a few unique ideas in the fan hacks for Brawl). I think Roy is often sold short in terms what kind of character he can be.
On a sidenote pertaining to FE, I just beat FE5 again. I was going for a an A-rank, and ended up getting a SS rank, and that was even when I made some major errors in a few of the chapters (could have cleared them a lot faster, but minor errors in previous chapters compounded into big ones later on). I really can't believe I got the SS rank considering that I actually had a lot easier time beating FE5 this time around than when I was simply playing to beat it (I did that twice with FE5).
I beat the game very quickly, although there were a few tough spots still here and there, overall I had a ton of fun with it. Its easily a masterpiece and superior than most games in the series. I really love how much strategy is involved (this becomes especially obvious when you are going for a high-ranking run). The final chapter took a lot of ingenuity (and a lot of luck!) to finish quickly (before the reinforcements come and start picking off your under-leveled units).
I also learned a newfound appreciation for the formation option. This feature was introduced in FE6, however, I can't tell you how much harder several chapters were (especially the final one and chapter 20) due to the fact you can't choose where your units are on the map.
FE5 is a masterpiece. Its easily the best of the Super Nintendo Fire Emblem games, and has a lot going for it. I really love the atmosphere and character designs (I just adore the artwork that is shown in the ending credits for this game). The only other FE I have had as much fun going through as I have had with FE5 is FE6. The character designs (especially the outfits) are actually practical and look really cool (takes some notes FE13, women don't go dressed up as whores when they go to war).
I am also really enjoying that Sound Test I just unlocked (I only needed an A-rank to unlock it, and that was all I was shooting for, but ended up doing far better), especially considering how much I enjoy the soundtrack to this game.
Also, I am glad that someone posted a link to my FE6 Roy post when yet another post brought up "Roy should not be back cuz he sux". I appreciate it.
Its amazing how much mileage this topic has despite there not being any new information about these FE characters since basically a year ago.
