Comicave Studios have announced that their SDCC 2016 exclusive will be this Omni class 1/12 Mk42 Iron-Man, complete with Sofa accessory.
"Omni Class 1/12 Scale Iron Man Mark 42 with Exclusive Leather Sofa set is coming to you first at San Diego Comic Con 2016 this July."
No price or other details as yet, but the Mk43 retails at $115 (£80) so I would estimate around the $150 mark upwards for SDCC.
Comicave are also kicking off a celebration of Captain America this month via their social channels, and this will cumulate in the reveal of a Captain America SDCC 2016 exclusive item of some kind.
For those unsure of the Omni class, then this is the detail from the Comicave Studio website.
