Is Wal-Mart interested in buying Vudu?

It is no secret that we're big fans of Vudu's HDX streaming around here, in fact it is the only internet delivered HD we've ever enjoyed. At the same time we're not big fans of Wal-Mart because no matter how cheap the prices, we've had a number of issues with the level of service. So we're not exactly sure how we feel about the possibility that the two might be getting together. We really don't see the upside here either as Wal-Mart is so big, why would it want to buy Vudu. The only thing we can think of is that Vudu isn't sustainable on its own, so it needs a big brother to funnel money into it. So yeah, we don't really get this one, so hopefully it just remains a rumor.
