Update: it seems that the 970V model will be the stand model and the 975V will be the wall-mounted model. The OLED panel itself will be the same in both models.
The European Imaging and Sound Associations (EISA) has selected LG's upcoming 55" OLED TV for its European Display Achievement Award. Interestingly, EISA named two different models - the 55EM970V and 55EM975V. When LG launched its OLED TV, they named the model 55EM960V (in the US it will be called 55EM9600). So not only did they change the model a bit, they will also have two different ones. The difference will probably be small (as the difference is slight).
