I also hope for a little scene. Better than nothing, I'd say. And I feel a bit stupid for this quote, but "Actions speak louder than words". If we do not get a confession, which I don't doubt at all, there's probably the action that can spell it for us. Hug, head on shoulder, etc. For EdXWin, we need this, because their actions is where we get most of the hints, whether it be facial expressions or movements of the body. Or at least in my view.
Yes, Ed shows his boxers in front of Winry, and by the looks of it, it means nothing to them. No, nervousness or any of that sort. Extreme comfort level. Still, I had never seen a guy in his boxers prancing around inside my house.
Al has to get a girl sometime. Whether it be now or we might never see it, he is getting one. He won't stay single forever.
Now, about this thing of Ed and Winry thinking of each other as bro and sis and other topics discussed. I haven't had much of a chance to get my word in and stuff, so don't mind that it's behind. I want to express opinion too.
1. They are not really related. They grew up together and the bond they make while growing is what makes them like brother and sister.
That is the real meaning of it. They are more like childhood friends with that definition. If they cross that line of caring, loving, and protecting like your related and platonic, is nothing bad. It kind of represents incest, but it is not incest in its most nor is it true. Thus, there is nothing wrong.
They don't share families and bloodline.
Besides, if that does happen, they didn't really think of each other as bro and sis deep down in the first place IMO.
Think of each other as brother/sister broken in the manga, by Winry. All we need is Ed's point of view and we're good to go.
I'm not saying that it's total BS, it does have its point, but it's not to take seriously, and I can tolerate this one, cause it does make a sense. This could place many arguments and is hard to think about. Thing is, they are not related. As long as that remains true, nothing could happen. And same thing for AlXWinry fans. If they think this of Ed, why not Al too? Yet, they think is right. Which comes to another thing.
2. Personality.
They keep saying that Al is kind, and has a good personality, and show he cares, has reasoning, and yada, yada, yada, yada. Which shows, that he is capable of settling down with Winry or a girl. OH! But no, not Ed, because he doesn't think of it, is a lone wolf, travels too much, has too many goals, and because of this and many more, we cannot see him with a girl.

This goes to his fans, who are mostly female, and I do not know why doesn't that fit them too, unles your a cross dresser.
First of all, Ed is human. HUMAN. Not only that, he's a MAN or BOY or whatever you want to call it, with HORMONES. He will be attracted to the opposite gender and you saw it, for those who paired him up with someone else for their reasons. And no, yaoi don't count.
The only goals he has is to get his and Al's body back and track the philosopher stone. What then? When he accomplishes his goal, what is he is going to do? SETTLE DOWN. The only reason he's traveling is for that specific reason, and his lone wolf attitude is not exactly true. He doesn't want to put anyone else in danger, not to mention, that he can't trust anyone, not even the military, with the activities going on around him. People even say that to him.
Once all this is over, wouldn't he want to start a family and live peacefully? Or to only watch his brother living that life only, and he's is in God knows where, while Al is happy, and raising his children.
That's unfair, and terrible, terrible reasoning.
3. Fangirls- Don't want to go there. I love Ed and all, but....

Unless you get animated or through some weird seizure Ed comes to life, you won't be touching him except in your imaginations and fanfics. So, it's better to let them dream.
If there are things I missed, I don't even want to know. Cause other than #1, everything else is crap. I know people will disagree and I'm gonna get flames, but whatever. Just don't judge me by this.
