Probably because a system's life span is quite a few years and they want to be able to have enough titles to last those years. Releasing everything at once would make people ignore everything that isn't Mario, Zelda or whatever other classics that system has.
So I played through the Crush3D demo, aced all three levels with all rewards. It's cool, but if that's all there is to it, I'll wait for a price drop if I purchase it at all. The production values are good, but that could have (and probably should have) been designed as an eShop game.
By the way, I compiled a long list of everything* that got updated over the course of the week/yesterday. For those that care:

I know not everyone is an ambassador, but seriously. Only games and for those who already own metroid, one one game is made available. And sorrry, demos do not count. Like, wtf? Not that I would download and buy games weekly, but this is pathetic.
Nope. Mine refreshes pretty regularly. I haven't had that come back since they started selling all of those videos on the eShop. Maybe try deleting and re-installing the channel? Or is there an update available?
