Is Sebastian Stan’s latest Instagram post a ‘Captain America’ hint?

Marvel‘s Winter Soldier just shared a very intriguing photo on Instagram.

Sebastian Stan posted a picture of himself with a replica shield from Shield Labs, decorated with the Winter Soldier’s red star logo instead of the traditional red, white and blue Captain America color scheme.

Since Sebastian Stan’s Winter Soldier and Anthony Mackie’s Falcon are both in the running to become Captain America after Chris Evans. Could this be a hint about Stan’s future role? Or does he just feel like teasing his fans between movies?
