As we featured in a below post, Indigo Studios are Hasbro/Nerf's choice for package design. I had a look at their design portfolio online and I think I nearly pee'd myself in excitement; check these out!
That being said, chances are these ARE just design concepts, but HO-LY crap this would be some exciting stuff if these made it into production. The Spectre looks amazing in Whiteout colours..
Sonic series is cool and all, but I have to admit that any blaster that's released in the new Whiteout series is going to be on my Santa list this year..
Update: Unfortunately, the portfolio has been taken down. I'm not sure why this has occurred, but it reiterates that it's most likely these images in their portfolio are just demonstrative of what they can do, rather than it actually making official release. Please don't hound them for info- they're designers, not manufacturers.
