Walmart an option?

I haven't had internet for a long time and I know I've missed a lot about Sin's progress. Is this game going to be sold on the mass market, in stores like CNA or Walmart? Is it going to be just a place your order 'because you part of small niche of gamers'? A game like this would sell out if people knew about it, but if people don't and it's just the few of us who do, then there would be no point for me waiting for it to be on the shelves of a local store and just pre-order it. If it is going to be sold on the large market of things then will it be sold overseas to international game stores, in contries like say, in South Africa?
