I remember when the news first hit. My kid bro sended me an sms with simply 4 words: Marvel vs Capcom 3.
My excitment was beyond words.

And now, like everyone else, I've been hoping for some exciting new characters and returning favorites. So far, many of my wanted new guys have been added (Dante, Deadpool and Thor (The God of Thunder, man), but I'm a bit dissapointed that not many of my faves are returning.

So, I decided to make a wishlist. Here are the New and Old characters I would like to see duke it out in this new brawler

NEW
1. Nightcrawler
This Fan-Favorite X-Men needs to be included. Give him some nice moves focusing on teleportation and speed and you'll have one fun character for the team.
2. Demitri
The Darkstalkers was pretty well represented in the last game with Morrigan, Anakaris, Felicia and B.B. Hood. But where was the cool vampire Demitri Maximoff? He's badass and must be added to the cast.
3. Nico Minoru and/or Victor Mancha
If you haven't read Brian. K Vaughns Runaways series, you should. Right now. It's one awesome comic. Out of the runaways there are two of them I'd really would like to see. The staff wielding Sorceres Nice and the awesome Cyborg Victor. Victor would have awesome powerful moves to boost and Nice would duke it out with her "Staff of One" and some mad magic powers. Plus, if she's added, I could create a Bo-Staff team consisting of her, Gambit and Son Son.
4. Alex and Ibuki.
The Street Fighter 3 series didn't boost any players last time around in MvC2.This needs to be fixed. And since Alex was in Tatsunoko vs Capcom, I think he should be in MvC3 as well. And Ibuki has also apperaed outside of SF3 (in SSF4). So she should join to.  
5. Juri
Street Fighter 4 introduced some New Blood to the SF-universe. Out of all the new ones, Juri is by far the coolest and most interesting. Like Alex and Ibuki are needed to show of fighters from SF3, Juri should be representing the newer fighters from SF4. If not adding her, than please add C. Viper of Abel, since they are pretty cool two.
6. Daredevil
Old DD is one of Marvels most well know characters, but has never been in any of the Marvel fighting games. I think he'd be a great addition to the franchise. I'm placing him low on my wishlist however, since I don't find him as necessary as bringin in the other new guys (And my top three classic characters).
7. The Whole Final Fight Gang
That means Cody, Guy and Haggar. All three of them. I can understand if Haggar won't join since he's to similar to Zangief. But the Blonde and the Ninja would be a nice addition.

RETURNING FAVORITES
1. Gambit
My main-man since day one. I've had a bunch of different teams but Gambits always been my most trusted sidekick. Call him my lucky rabbits foot or whatever, but this guy has to be in the game. ROYAL FLASH!
2. Cable
If Capcom doesn't include this guy they will alienate a LOT of old fans. Look at the professional players, the ones who top the tournament list. Nearly everyone of them uses Cable. We need him. Hyper Wyper!
3. Akuma
I love the Ansatsuken-fighters (Ryu, Ken and Akuma). Sure, my favorite is Ken for most games, but in MvC, my fighter is Akuma. Lightning Hurricane Kicks, awesome Shoryukens and a shower of hadoukens from the sky? The Fist Master is one of my maincharacter, so of course, I'd like to see him return.
4. Guile
The original armydude never was a favorite of mine in the Street Fighter games. I'm just not very found of charge type characters. Is MvC2 incarnation however is epic and such a hoot to play as. Bring back the armydude, Capcom, please?
5. Juggernaut
Yes. THE tank of fightinggames. This guy needs to join the fight once again. They've already added the Hulk, let's add another Big Guy for those Clash of Titans fights we all love so much.
6. Son Son
Adding this monkey chick to my wishlist because I'm a bit worried she won't return, and she's my kidbros favorite character. So it would be sad for me if she didn't come back for part 3. Plus, she's funny.
7. Strider
Not one of my main characters, but this cool ninja is just a necessary addition. It wouldn't be the same without him.

NOTE: The Reason I didn't add Spider-Man to the wishlist is because he's pretty much selfwritten as a character. Afterall, he's Marvel flagship character. Not including him would be just stupid.

Now, I have only one more thing left to say to the guys at Capcom.
