13AM Games has given us an update on this Amazon listing:
We're happy that people are excited about the possibility of a 3DS and retail version of Runbow, but we have to make it clear that this leak is not from 13AM Games and unfortunately contains some misinformation. I wish I could elaborate, but all I can say at this point is that we hope everyone can tune in to E3 this year where 13AM Games will be making some cool new Runbow announcements!
Thanks for the passion and the excitement - Runbow fans are the best.
So there you have it, the listing isn't entirely accurate, but the studio has plans for E3 - we'll certainly stay tuned.
Amazon, the retail giant, is a source of more leaks than a sketchy plumber that doesn't know what they're doing. It seems that the retailer's US site has leaked an utterly fascinating physical retail release for 3DS.
13AM Games hasn't revealed it yet, but Amazon's listing is for Runbow on 3DS (hat tip to @Wario64 for the spot); it's priced at $29.99 (or $23.99 via Prime) for a release date of 6th September in the US, with Nighthawk Interactive listed as the publisher.
Intriguingly, and perhaps reflecting the price, it's described as a 'Deluxe Edition' which includes all DLC:
The Runbow Deluxe Edition includes the critically acclaimed Wii U party game with all the DLC. New DLCincludes new levels, costumes/ characters, game modes and more! Runbow is a fast, frantic game for 1-9 players that will keep you running back for more. The world changes with each swipe of the background, so you'll have to stay on your toes as platforms and obstacles disappear. If you can't see something, it doesn't exist. Play with up to 9 friends locally or online. With hundreds of levels, dozens of costumes, and more indie guest characters than you can handle, you better get ready to Runbow!
It's certainly pleasing if the Wii U game is indeed getting ported, and we'll also be curious to see whether an equivalent boxed version for the home console will arrive; none have been listed at the time of writing.
Would you be tempted to pick this up on 3DS, assuming it's not an elaborate falsehood on Amazon's part? Let us know in the comments.
