Production issues for 360 GTA V. (Nu.nl, Dutch source)
According to several Dutch retailers there are some light issues with the production of the 360 version, as apparently two of the ten lines for the 360 version weren't functioning properly. Two Dutch retailers have stated that their initial shipments have been cut by a third due to this, and Nedgame, one of the biggest in the Netherlands states that their shipments have been cut by 10%. This'll prbably not make any difference in sales, but I thought it was worth sharing.
