Here are some pictures from SneakyDan who is being sneaky and sending me photos (nothing lewd...). We have some close-up shots of the Stormraven! and confirmation of Grey Knight usability (if you didn't know already...). Check the pics out and Dan's thoughts...
"After my initial hatred, I friggin love this thing up close. It's front heavy, but it's got that "GRAVITY DOESN'T APPLY TO SPEHSS MAHREENS" look to it. Confirmed for grey knights as well, saw the door icon kits"
That kid looks pretty evil...and I again think the other angles make it look pretty good (I particularly like it's rear). Who's buying one? lol
