This is a good thing for Nintendo to have done
The best thing XBOX ever did was to make EVERY download title have a demo, it makes total sense on every level and has probably been the major cause in indie and XBLA titles outselling anything on PS3 and Wii.
Nintendo whom i love to bits absolutely suck at anything online, like EVERY jap developer they are so far up their own arse that they just don't get how important this component of modern gaming is..... I'm the biggest hater of multiplayer gaming etc but what i know for sure is that people especially now in this financial climate want to have a sneak peak at stuff before handing over their cash.
The WII U will need to look at what their competitors do and quite frankly cut & paste, the old Nintendo way won't work anymore and theres no way the amount of people who bought a Wii will buy another nintendo console, the vast majority of Wii owners are casual gamers or part time recreational gamers so they should not expect brand loyalty from these folk, they wont get it.
Full marks to nintendo for doing this for the Wii, maybe its a sign of what is to come, i certainly hope so and i hope they ramp it up for the WII U, i really want one of these new consoles and the more stuff thats added as standard the more it will be attractive to those who dont really care right now.
Fingers crossed for a great Nintendo year
