Not entirely sure. I honestly believe I've read several versions -- Xbox only, Xbox game points only, and all Microsoft products. Regardless, that should be a big enough market of geeks and this is the right season for introducing such -- if Microsoft was going to move the dial even slightly on purchasing of Bitcoins we'd have seen at least a slight uptick in buying activity already (even if there was countervailing selling activity as well). But, here, we have no volume. Nobody was crazy enough to bite and buy BTCs for this purpose. Thus, the only people who will be utilizing this, at least generally speaking, is existing bagholders.
