Digital game sales are cool. You know, that fairly basic industry practice that Valve, Sony, and Microsoft have been doing for years? Well it looks like Nintendo is going to join in on the fun, and offer a weekly sale on "select games" on the eShop -- just like they recently had with Mario Land, this is presumably a "one game a week" type of deal.
In the short-term, the only problem I see with this is that Nintendo isn't exactly transparent when it comes to telling people about special offers. Club Nintendo updates their offerings monthly, and through an internal press release we get the weekly Nintendo downloads. It's something, but not as transparent as Steam's giant sale pages (and this gem), Sony's frequently updated PSN blog, or Major Nelson's announcements.
