Nintendo puts out catalogs like these all the time. In English even. There's like four different ones every year (one for each season). They talk about all the latest games and products that Nintendo wants to push and have screenshots and release dates. They're pretty awesome, and back in the pre-internet days of Nintendo Power and GamePro, they'd have been considered to be 100% pure liquid megaton.
They're free, and available to the public. If you can find them. Usually around larger events. Like most promo material, it's collectable in certain circles, so it probably gets on eBay every now and then, but they tend to evaporate quickly, and anything more than a month or two old is half-impossible to find.
