I was looking through the trade-in deals at GameStop (in Sweden) and they apparently accept "Bomberman" for "3DS". I'm not sure whether it's listed in other countries too.
In any case, it must be a mistake. It's probably meant to be "DS", but a typo alone can't explain it as it's also found in the 3DS category.

Here's a link. It's on the last page.

It must be a mistake, as the game was never released. There is a game called "Bomberman" for the DS, though, so maybe that was the title that they were referring to, and it was mistakenly placed in the 3DS category (it's only one character off, namewise).
