A reply I got from IN on Facebook has made start doubting the current power discs listed on the official site, and the number of waves.
I said that since the torn discs with texture and sky have only been exclusive and are not in the third wave (the wall-e texture and sky are the only ones in the third wave) the torn discs will never be released in my country (The Netherlands) since we don't have those stores here. To which I got a reply saying that the Tron discs are yet to be released but are coming.
Which raises the obvious questions when, where and how.
I am getting the feeling now that there are some things they aren't telling. Such as a possible 4th wave.
They won't add extra thing to the game. But they can definitely add the ones that are already in it.
And they most likely will.
