Deadpool 3 Promo Poster Features Another Major X-Men Character

For quite some time, rumors have swirled about numerous characters who may or may not appear in the Merc With a Mouth's next big-screen trip, but we've only seen two (Sabertooth and Toad) with our own eyes, courtesy of some leaked set photographs. However, it appears that a specific winged mutant from the original crew may possibly make an appearance.

Wade Wilson (Ryan Reynolds) is depicted beside Wolverine (Hugh Jackman), with a mysterious silhouetted character taking flight in the sky above. Is this Warren Worthington III, also known as Angel or Archangel? They don't appear like Angel's wings (natural or after Apocalypse finished with him), but he does seem like the most likely candidate (we'll presume it's not Sam Wilson/Captain America).
