It's pretty clear, the VFX tracking markers for Shawn R. Ashmore's Iceman are just on his face as he's wearing a leather jacket/hoodie in the snap above, not a full body VFX suit like the one Mark Ruffalo wore in The Avengers for The Hulk. This PROBABLY means Iceman will look more or less how he did in X-Men: The Last Stand. Some fans have clamored for Iceman to have a full-body ice coating in 'Days of Future Past' but that doesn't look to be the case here.
Note: Motion Tracking is the process in which software tracks a point (motion tracking marker, the orange triangles on Shawn's face) and helps the computer transform real-life geometrical contours, curves and movement into stunning computer generated visuals. What will those markers on Shawn's face turn into?
