So I've been lurking here without an account since...2012, I think? And this is the post that finally forces me to join up and comment.
Yes. This. A Lego Orca has been something I've been hoping for since I first heard Overwatch would be a theme. I'm a huge fan of system scale ships and done right (with a price point around £100/£120) an Orca would be a day #1, waiting in line outside the Lego shop purchase.
Also - "stairs leading to the front cockpit". X'D I hope for the day that Lego will get that right - when my minifigures won't have to climb outside of their Quinjet, Millennium Falcon or Orca and make a wing-walk in order to reach the controls...
