I feel like Cap 2 will finally do justice to the character. Evans is a great actor and he'll have the support of ScarJo. Give him a good script and magic will happen.
Don't forgot Sebastian Stan, his 6-movie deal suggests Marvel has bigger plans for Winter Soldier in the future too, I'm quite optimistic they won't pull an Iron Man 3 alteration to his character or kill him off. It'd be amazing if Bucky appeared in SHIELD too, Stan was in television before so I'm sure he'd love to make an appearance if asked.
I like how passionate he's about the character, dude apparently looked at Cold War docs/spy movies and researched brainwashing techniques.

This suggests that the Cold War/Russia will still be a big part of Bucky's past, I'm interested to see how they adapt the cryo-freezing thing though.
I'm still salty in The First Avenger how they made HYDRA a Red Skull organzation instead of him being Hitler's Nazi right-hand man which is he should have been, for the merchandising toys they could have just replaced the swastikas with that logo so they'd avoid controversy. I would have made Hydra a smaller tech company based out of Japan (like they should have been) who were under Skull's eye, but not a massive bloody army (think WWII AIM).
And Evans nailed Cap in the first movie perfectly, it wasn't his fault that the second half of the movie when Steve went overseas was so lackluster (I have so many ideas on how they could have fixed it, as I mentioned above). The Human Torch easter egg was amazing though.
