With the advent of HD it may mean no more region coding on DVDs. Before it was NTSC (USA) versus PAL (EU), but now there is HD is, a universal transmission standard. This will trickle into the next generation of video game consoles, but the question posed is if importers will take advantage of this? Sony recently experienced this issue with its non-region based PSP. There were delays in its EU launch and foreign importers brought in US and Japanese PSPs. Sony has since taken them to court.
Apparently, HD is not only changing how we watch TV, but how these conglomerates do business.
