Retailer listings for unreleased games should never really be taken at face value - they're prone to mistakes and errors, and have led to many red faces in the past. However, there's sometimes an element of truth in them as well, and we imagine that many people are crossing their fingers that this is the case with Swedish retailer CDON's listing for the Wii U version of Grand Theft Auto V.

Given the fact that CDON isn't exactly a well-known force in the field of video game retail, it might be prudent to hold back those feelings of elation, but it's not as unlikely a scenario as you might imagine.

First up, Nintendo has relaxed its stance on 'mature' games over the years, and even permitted Rockstar to release GTA: Chinatown Wars on the DS.

Secondly, it's highly likely that many third party publishers are eyeing the Wii U with interest, and may have already begun porting over forthcoming games for release on the system. Why? Because they don't want to be caught with their trousers down if Wii U repeats the Wii's success and becomes 2013's hottest ticket.

Keep this in the 'rumour' bucket for now, but we personally don't think GTA V on Wii U is as far-fetched as many would have you believe.

Here's a screengrab of the listing:
