Do anyone know if the VGChartz tracking for PSP is UMD sales onyl or it's UMD + PSN sales? Since PSN version of the game is rising in popularity because they are cheaper than the real counter part. For example, Valkyria Chronicles 2 on the PSP was 5,500 Yen retail, and only 4,500 on PSN. Anyone know the answer to this question?
