I asked our devs to clarify this, just to be sure, and your IP only matters during purchase. Afterwards you just keep access to the game you paid for. TW2EE will technically replace TW2 in our catalog, so the "rest of the world" version of TW2EE will replace your version of TW2.

As for downloads - you keep your access to the game you purchased, regardless of your current location.

Also, download attempts aside, I'm pretty sure we wouldn't be able to check your location at the time of the switch to the Extended Edition, no matter how much we kept zooming and enhancing. ;)
