It's Christmas time, and you may need to be afraid if you're after a red 3DS, according to a report from MCV.

The trade magazine claims UK retailers are struggling to keep the red 3DS in stock in the run up to Christmas, with other colours also tough to get hold of. The releases of Mario Kart 7 and Super Mario 3D Land and a high-profile advertising campaign have all contributed to an increase in sales for the portable, with GAME Group's Iain Johnson hoping there's more to come:

We have high expectations for the final few weeks before Christmas.

We all do, Ian. We all do.
